[ engine revving ] [Mike] Hey, welcome to Music City Trucks. Well we're doing something a little bit different today. Day one of a new project and we're gonna thrash this thing out here at Beech Bend Raceway Park at the Pro Touring Truck Shootout. Anthony tell them about this truck. [Anthony] I'm real excited about this one. What we've got today for you is a '72 Chevy C-10. This is a long bed truck and we're fixing to do quite a bit of work to this one. I'm real excited about it. [Mike] This thing out here at this shootout is like a fish out of water. We're the most stock truck out here and one of the longest. It should be funny on how this thing's gonna navigate this road course deal and these cones. I think it should be a real fun time. [Anthony] I think we're gonna have a fun time on this track and who knows. Maybe we'll set a track record or maybe not. I don't know. [Mike] Right now it's rainy and we've got street tires, poor throttle response. The conditions might be coming to us. We've got them right where we want them! We're gonna get in the gate and pull up here. Next thing we've got to get this thing teched in. Make sure she's all pass. All the rules, regulations, and stuff. Then we're gonna go run this thing through the road course and see what it does. The Pro Touring Truck Shootout started in 2019 when a passion for trucks and improved performance collided with a truck enthusiast and an idea. [Arnie] I saw the trucks becoming more and more popular, especially with the aftermarket components because they were playing second fiddle to the pro touring cars. The Camaros are great but they're expensive to build. You want mama to sign off on the entire project. So taking papa's truck back from the garage to restore it with an LS motor and $50,000 dollars later these trucks were born. Then we have at the same time the aftermarket industry catching up saying we have a drop kit but what about a coil over kit? What about adjustable coil overs? Now we have something that could perform and a little bit less maintenance as you drive because air bags, you've got to pay attention. Coil over system you get in it and drive. Then these guys are like let's put some seats in it and some seatbelts. Plenty of these guys have slid over on their bench. I said this is getting a little bit crazy. The truck is hooking. All of these challenges that came with a reward or they won now other guys want to be like other guys. [Mike] This vision sparked with the growth of the pro touring scene led to the adrenaline pumping, fast paced, super competitive racing we have today but keeping the sense of camaraderie within the truck community. [Arnie] Everyone is great smiling but when they get that helmet on and the engine turns on it's on. Everyone here can cut up, hang, and just have a good time but when that truck is in gear and that light changes at the autocross there's no friends. It's not bad. There's other competitions that people get angry. These guys are still low key but when it's on it's on. [Mike] One of those competitors is last year's winner Tyler Gibson in his unassuming '73 International Harvester Scout Two on an S-10 chassis. Between the frame rails is a 400 small block Chevy power plant attached to a smooth shifting T-5 manual trans. He was bitten by the race bug as a teen and has been competing ever since. He loves the challenges this event has to offer. [Tyler] It's challenging because there's different aspects to it and today we're dealing with the weather and different track conditions. It's super slick out there this morning. You have to excel at the autocross. Normally it's drag racing. I think we're gonna do spectator drag racing around the circle track. So that's gonna be completely new for me. Then speed stop, that's probably my Achilles heel. I'm okay at it but it's not my thing. I haven't done it as much. I would struggle at that a little bit. So excelling in all the different events is the challenging part. Making it through the weekend and not breaking anything. I blew up a few engines here in the past before I won. [Mike] Being the back to back champion has put a target on Tyler's back but he still feels the truck racing family is a unique one and enjoys the competition. [Tyler] Truck guys and everyone that we race with, they're the best. Everyone's competitive but you also find people helping each other out, giving each other advice. It's the best racing community that I've been in. [Mike] To keep the event and sport growing Arnie uses his passion and truck to get even more people involved, putting them in the seat and on the track. [Arnie] First person I'm taking a ride with. I've gone out there and had fun with them and I never knew. You're out here as spectator going okay, it's fun. It's like driving on the highway, it's not. Left, right, acceleration, braking power. Everyone comes out going I didn't know. Then they get hook and the wheels start turning, plan starts getting formulated, and before you know it another truck is born. [Anthony] The C-10 hits the track ready for a time attack.
[Mike] Once the rain cleared we were able to roll our truck to tech. Being the longest truck there she didn't quite fit on the scales but it was enough to get the red dot of approval. Next stop was to get in line for our turn to shine. [ Music ] Here we go! Anthony letting her rip. Hard right, hard right! There you go. [ engine revving ] Now we're gonna slalom. Go back and forth. Easy, easy, easy, easy! You're gonna have a hard right. [ tires squealing ] [ Music ]
[Mike] There you go. Hard left, hard left. [ Music ] That's it, woo! 68:54! [Anthony] Alright! Holy $#@% that's a big steering wheel. That was fun! [Mike] Now it's my turn to see what we can do. It's pretty slick but this old truck, she wants it. So we're gonna let her hang out and see if we can beat that 68.5 or something like that. We'll see what we can do. [Anthony] Let's see what you got Mike. [Mike] Here we go. [ tires squealing ] [ Music ]
[ wind noise ] [ Music ]
[ engine revving ] [ tires squealing ] [ Music ]
[Anthony] You got it. [Mike] 68-0, woo! That was rough. [Anthony] Felt like our seat might have broke. [Mike] What's flying around in here! [Anthony] A few too many G's for the old C-10. [ Music ] I want you to hold me! [ Music ]
Well that was fun. [Mike] This thing, it's a blast out there. That huge steering wheel. You're all over the place making them quick turns. This thing, it may not look crazy on the outside but from the inside it's fun. [Anthony] It honestly did much better than I thought it would do. You can kinda stand on it the whole time and it does what you want it to do, point and go. [Mike] It's got very low power. It's an open differential, and I think that's helping us out there with this rain and wet track conditions. We thought we'd bring it back to the pits. Make some adjustments. Some of these fast trucks out here are adjusting shocks and moving weight around. We can't get that technical. I think we can do some air pressure adjustments and let her rip again. [Anthony] What'd you run, 68? [Mike] I was 68-0 and you were 68-5. We were both right there together. It's nothing as fast as the fast trucks out here. [Anthony] We knew what that was gonna be. We knew we had no chance to compete with those guys. [Mike] Our class, the stock class, we're really close. I think three seconds quicker was another one. It's super fun. Let's do some adjustments and do it again.
This looks like a big restriction. So let's take this thing out. Oh man, look at that air filter. That thing's seen better days. We can get rid of that. That's gotta be worth at least seven horsepower. [Anthony] Maybe a second off the time. You don't know. [Mike] Get rid of all the excuses. I think we're good underneath the hood. [ Music ] [ compressed air hissing ] [Anthony] I let about a couple pounds out of it. It should be better. We'll see though. [Mike] This was a 30. That's got it all sideways. Perfect! Well we got a few adjustments done. Let's go stand on it. [Anthony] This thing's ready to rip. [Mike] Hey the parking brake was on. [Anthony] Make sure that thing's not on while we're trying to run it around the track. [ Music ]
[Mike] Well the track is really dried out. Rain has stopped. I think it's time to let it hang out. We've got to give this thing all the beans. Max cackle! Here we go. See what we can do here after we made our adjustments. Gotta beat that 68-0. That was our last time. We'll see what we can do here. [ tires squealing ] [ Music ] [ engine revving ] [ Music ]
[ tires squealing ] [ Music ]
[Mike] Woo! 65-10. Shaved off three seconds. I'll tell you what. We got it! She was making a lot of noise out there. She's still running. I got oil pressure. Let's let Anthony rip on her.
[ tires squealing ] [ Music ]
[ tires squealing ] [Anthony] There we go! [ Music ]
[Mike] Woo-wee! We put this thing through the paces today. [Anthony] We more than put it through the paces. I can't believe it's still running. [Mike] This poor thing. We have stressed it out. The engine, tires, transmission, but I think we got everything out of it. Got a lot of room for improvement. [Anthony] What do you say we get this thing back to the shop and get working on it cause I'm excited to see what this thing can become. [Mike] We can really turn this thing into a fast truck. [Anthony] Let's do it. [ Music ] [Mike] Coming up, we show you another way to check the health of your engine.
[Mike] As you can see, we got our C-10 back in the shop and the next thing I want to do is some engine testing. I think all that heat we put into it out on the autocross made our starter take a crap. So we had to change that first with a similar one to this one right here. This is a Duralast starter we picked up. These Duralast starters are triple tested before they send them out. So not once, not twice, but three times they test these things to make sure they're high quality. These will meet or exceed OE standards. These also are 100 percent new, this Duralast Gold. So everything inside of this is new. If you want to save some coin you could go with the remanufactured line to get that same high quality starter. So the next time you're in the need of these parts check out your local Autozone and pick them up. Now let's get to our testing. With our new starter installed we can get to our engine testing. I've already done a compression test on this engine. I showed you how to do that earlier on our OBS Chevy. The compression numbers on this it showed number three was the lowest of the eight of them. So our next step is to do a cylinder leakage test to find out what's going on with that one. That's gonna be the subject of today's Summit Tech Tip. For our engine testing tools I went to Summit Racing and picked up one of their combo kits. It comes with a compression tester, the cylinder leakage tester, and also an automotive stethoscope to help you diagnose your engine. To get going on our cylinder leakage test we'll get our adapter threaded in to number three cylinder here. What you want to do is make sure if you're testing number three like we're gonna do you want this piston up a top dead center of the compression stroke. What I've done is to help identify what stroke we're on I went ahead and took the valve cover off and you can watch the valves, watch the rockers arms as you rotate the engine to let you know where the piston's at and what stroke you're on. So we're at top dead center compression stroke on number three. We'll get our adapter threaded in here to where the spark plug goes. Got that spark plug out. We'll thread this guy in. With our adapter hooked up we can get our shop air here and hook this up. Get our adapter and plug it in. [ air hissing ] [Mike] Now I'm gonna set my regulator. I like to do about 100 pounds to keep it even. We've got 100 pounds coming in and it shows about 80 pounds here. So there's a difference of 20. So 20 pounds or 20 percent leakage right there. Where that could be leaking from well your piston rings are not complete. They have a little end gap right there. So you're gonna have some leakage past the piston rings. That's just natural. You want to have as low as possible to help it seal up. Naturally you're gonna have some there. Other places it could be leaking, past the intake valve. So what we would do is come over and see if you can feel any air past the throttle blades of the carburetor or hear anything rushing. I don't hear anything there. So no leakage past our intake valve. The exhaust valve, if it was leaking we'd go to the tailpipe. Put our ear at the tailpipe and see if we hear any air rushing out the tailpipe. That would suggest a leaking exhaust valve. The other place could be a head gasket. So we would take the radiator cap off. See if we've got any bubbles, any air coming out. The cooling system suggesting a blown head gasket right there. This one so far it looks to me like it's all past the rings on this setup right here and that's typical with the wear on this type of engine. Hopefully these tests I've shown you can help you diagnose your engine. [Anthony] Up next, what surprises will we find while tearing out the interior of our Super Cheyenne.
[Mike] Alright, that looks good. Guys welcome back. We've been brainstorming a lot of different ideas and modifications that we want to do to this truck. [Anthony] Let us show you our plan for this Super Cheyenne. For our '72 C-10 this long bed is good for hauling lumber but we plan on hauling some ass. So we're gonna go ahead and convert the long wheelbase to a shorter, more balanced and better handling package. [Mike] Next we'll get our chassis in the weeds by installing an Air Ride suspension that'll keep us hugging the ground when we roll around town. Then to power our best we'll shelve the small block for a modern more powerful LS power plant. To keep cruising easy we'll keep the automatic mindset with a stout 4L80 to handle the 427 cubic inches of fire breathing fury. [Anthony] To help us stop we'll shed the factory disc and drum setup for a big brake kit. We'll surround our brakes with 20 inch wheels and 335s out back with 255s in the front. We'll give our interior a facelift as well as change the paint back to the original color with just a little added twist. Now that y'all know the game plan on the truck it's time to get it ripped apart, and that's gonna start on the inside. [Mike] As you can see, old pee-paw's plastic here over our seat protected it. It's actually a really nice looking seat but for our plans for this truck it doesn't match. So we've gotta get the seat out, the headliner, door panel, and we've got to get it off to the interior shop to give them some time to make their magic happen. [Anthony] I'm thinking we have them bolster this thing so we're not bouncing and sliding like we were on the track. Looking underneath it looks pretty clean. There might be a few treasures underneath the seat. That's always the surprise. [Anthony] I like a little extra pay. [Mike] That too! Some quarters, dimes, and nickels. [Anthony] You never know. There might be a hun-sky under there. I ain't holding my breath. [Mike] I highly doubt that. [ Music ] Let me follow you out. I'm too big for this. [Anthony] Watch your head. It's coming. Step down, very nice. [ Music ] Job well done. [Mike] Keep on going. I'm gonna have a seat. [Anthony] This ain't no union job. Let's get to work. [Mike] Soaking it in, alright. [ Music ]
Hey, look at that. What in the world? [Anthony] I bet you they lost it and had to go buy another. [Mike] Look at the imprint there on the mat. That's been under there for a while. [Anthony] We found something. [Mike] Let's get this headliner off. [Anthony] Doing my best not to jack it up. [Mike] Let me walk it out. [Anthony] It's definitely glued better on your side. [Mike] What happened was my side was in the sun all the years and I think yours was under the shade. [Anthony] I like that theory. [Mike] There she goes. [Anthony] That looks like original color doesn't it? [Mike] Yeah I think that's our target there, that color. [Anthony] On to the next. [Mike] Get these door panels off here. These are the fancy ones. I'm not really used to these. Bingo! [Anthony] You ready to get this dash pad out? [Mike] Get this thing out here. [Anthony] Couple of screws. [Mike] Of course they gotta hide this one right behind the steering column. [Anthony] Usually how it goes. [Mike] And away we go. [Anthony] I think it's ready. [Mike] Let's see if we can pop this thing out. [Anthony] Should come out a little easier. [Mike] Well we got the dash pad, we got the seat, the door panels, the headliner. All that stuff we've got to get loaded up and take to the upholstery shop. Get that going. That's all we've got time for today. [Anthony] The more I'm looking at this roof, four, five, maybe six inch chop. It needs at least that much. [Mike] While we're cutting we might as well cut the roof out of it. Put a sunroof in. [Anthony] What about a moonroof? I'm gonna grab a sawz-all.

The other place could be a head gasket. So we would take the radiator cap off. See if we've got any bubbles, any air coming out. The cooling system suggesting a blown head gasket right there. This one so far it looks to me like it's all past the rings on this setup right here and that's typical with the wear on this type of engine. Hopefully these tests I've shown you can help you diagnose your engine. [Anthony] Up next, what surprises will we find while tearing out the interior of our Super Cheyenne.
[Mike] Alright, that looks good. Guys welcome back. We've been brainstorming a lot of different ideas and modifications that we want to do to this truck. [Anthony] Let us show you our plan for this Super Cheyenne. For our '72 C-10 this long bed is good for hauling lumber but we plan on hauling some ass. So we're gonna go ahead and convert the long wheelbase to a shorter, more balanced and better handling package. [Mike] Next we'll get our chassis in the weeds by installing an Air Ride suspension that'll keep us hugging the ground when we roll around town. Then to power our best we'll shelve the small block for a modern more powerful LS power plant. To keep cruising easy we'll keep the automatic mindset with a stout 4L80 to handle the 427 cubic inches of fire breathing fury. [Anthony] To help us stop we'll shed the factory disc and drum setup for a big brake kit. We'll surround our brakes with 20 inch wheels and 335s out back with 255s in the front. We'll give our interior a facelift as well as change the paint back to the original color with just a little added twist. Now that y'all know the game plan on the truck it's time to get it ripped apart, and that's gonna start on the inside. [Mike] As you can see, old pee-paw's plastic here over our seat protected it. It's actually a really nice looking seat but for our plans for this truck it doesn't match. So we've gotta get the seat out, the headliner, door panel, and we've got to get it off to the interior shop to give them some time to make their magic happen. [Anthony] I'm thinking we have them bolster this thing so we're not bouncing and sliding like we were on the track. Looking underneath it looks pretty clean. There might be a few treasures underneath the seat. That's always the surprise. [Anthony] I like a little extra pay. [Mike] That too! Some quarters, dimes, and nickels. [Anthony] You never know. There might be a hun-sky under there. I ain't holding my breath. [Mike] I highly doubt that. [ Music ] Let me follow you out. I'm too big for this. [Anthony] Watch your head. It's coming. Step down, very nice. [ Music ] Job well done. [Mike] Keep on going. I'm gonna have a seat. [Anthony] This ain't no union job. Let's get to work. [Mike] Soaking it in, alright. [ Music ]
Hey, look at that. What in the world? [Anthony] I bet you they lost it and had to go buy another. [Mike] Look at the imprint there on the mat. That's been under there for a while. [Anthony] We found something. [Mike] Let's get this headliner off. [Anthony] Doing my best not to jack it up. [Mike] Let me walk it out. [Anthony] It's definitely glued better on your side. [Mike] What happened was my side was in the sun all the years and I think yours was under the shade. [Anthony] I like that theory. [Mike] There she goes. [Anthony] That looks like original color doesn't it? [Mike] Yeah I think that's our target there, that color. [Anthony] On to the next. [Mike] Get these door panels off here. These are the fancy ones. I'm not really used to these. Bingo! [Anthony] You ready to get this dash pad out? [Mike] Get this thing out here. [Anthony] Couple of screws. [Mike] Of course they gotta hide this one right behind the steering column. [Anthony] Usually how it goes. [Mike] And away we go. [Anthony] I think it's ready. [Mike] Let's see if we can pop this thing out. [Anthony] Should come out a little easier. [Mike] Well we got the dash pad, we got the seat, the door panels, the headliner. All that stuff we've got to get loaded up and take to the upholstery shop. Get that going. That's all we've got time for today. [Anthony] The more I'm looking at this roof, four, five, maybe six inch chop. It needs at least that much. [Mike] While we're cutting we might as well cut the roof out of it. Put a sunroof in. [Anthony] What about a moonroof? I'm gonna grab a sawz-all.
