(PAT)>> WELCOME TO ENGINE POWER AND ANOTHER CHAPTER ON OUR '63 GALAXIE PROJECT. TODAY IT'S GOING ON A LITTLE FIELD TRIP TO A CHASSIS AND FABRICATION SHOP IN NASHVILLE, TENNESSEE, WHERE IT'S GONNA RECEIVE SOME TRICK SUSPENSION COMPONENTS. NOW IF THIS IS THE FIRST YOU'VE SEEN OF THIS TIME

CAPSULE, HERE'S A LOOK AT OUR PROGRESS SO FAR.

(MIKE)>> THIS CAR STARTED OFF AS A RUNNING, DRIVING STREET CRUISER PAT BOUGHT SEVERAL YEARS AGO. THE BODY IS A TIME CAPSULE BEING SUPER SOLID WITH NO ROT ANYWHERE. NOW WE PLAYED WITH IT ON THE CHASSIS DYNO, WHERE IT MADE 328 HORSEPOWER AND 347 POUND FEET OF TORQUE. AFTER THAT WE STARTED TEARING IT APART. ITEMS TO GO WERE THE DRIVESHAFT, EXHAUST, AND THE THREE SPEED MANUAL TRANSMISSION. FINALLY THE SMALL BLOCK FORD CAME OUT AND REVEALED A LARGE

ENGINE BAY, WHICH WAS A WELCOMING SPACE FOR A POTENT POWERHOUSE WE BUILT HERE IN THE SHOP. IT WAS NAMED "LITTLE BLACK AND BLUE", AND IN ITS FINAL ITERATION THIS SINGLE TURBO 347 CUBIC INCH SMALL BLOCK MADE OVER 800 HORSEPOWER DURING SOME LOW BOOST BREAK IN RUNS ON OUR SUPERFLOW DYNO. BEFORE IT WENT IN WE UPGRADED THE STEERING WITH A RACK AND PINION SETUP AND A BRAND NEW STEERING COLUMN. ALL RIGHT, HERE WE GO! THEN CAME MOCK UP TIME FOR THE ENGINE AND TURBO. NOW WE POSITIONED THE ENGINE AND FABRICATED SOLID MOTOR

MOUNTS TO KEEP IT IN PLACE. THEN HEADERS WERE MODIFIED AND THE TURBO WAS MOUNTED SO WE COULD GET AN IDEA ON ROUTING OPTIONS FOR THE PIPING.

(PAT)>> THAT IS A NICE JOB RIGHT THERE! BEFORE ANY ASSEMBLY HAPPENS THE CAR WAS BROUGHT HERE TO COFFEY FABRICATION AND RACE PREP IN NASHVILLE, TENNESSEE.

(MIKE)>> THIS IS WHERE AWESOME PROJECTS ARE DESIGNED AND CONSTRUCTED. NOW THEY HAVE BUILT MACHINES FOR THE DRAG STRIP, THE SALT FLATS, AND EVEN THE STREET NO MATTER THE BRAND.

(PAT)>> FOR INSTANCE, THIS PRO TOURING CHEVELLE THAT HAS A SIX SPEED TRANSMISSION AND 800 REAR WHEEL HORSEPOWER FROM THIS TURBOED LS BULLET. NEXT UP ARE SOME INJECTOR UPGRADES, A BETTER TUNE, AND GENERAL MAINTENANCE FOR THIS RACY PORSCHE 996, AND HE EVEN HAS THE BIZARRE. A LAKESTER SALT FLATS CAR BUILT FROM A STRETCHED F-16 FUEL TANK THAT WILL BE POWERED BY A BLOWN BIG BLOCK CHEVY BURNING ALCOHOL WITH A GOAL OF OVER 300 MILES PER HOUR. WHEN THEY HEARD ABOUT THIS PROJECT THEY JUMPED AT THE OPPORTUNITY TO HELP US OUT WITH THE NEXT CHAPTER IN THE EVOLUTION OF THE GALAXIE, FROM A BONE STOCK CLASSIC

TO A RADICAL BUT STILL STREET DRIVEN RACE CAR. CHRIS COFFEY IS THE MAN BEHIND THE NAME. HE'S A TOP NOTCH FABRICATOR AND CHASSIS TUNER.

HE'S THE ONE WHO MASTER MINDED THE TYPE OF SUSPENSION, THE MEASUREMENTS, AND THE PART SELECTION.

(CHRIS)>> I TALKED WITH CHRIS AT CHRIS ALSTON CHASSIS WORKS, AND BASED ON WHAT YOU WANTED OUT OF THE CAR WE CAME UP WITH A GOOD LIST OF PARTS TO PUT THE WHOLE SETUP TOGETHER, AND MAKE IT EXACTLY WHAT YOU WANTED. THIS TYPE OF SUSPENSION FOR A LIVE AXLE IS ABOUT AS GOOD AS IT'S GONNA GET. YOU HAVE A WATTS LINK SETUP AND COIL OVERS.

THE TORQUE ARM, BASICALLY IT SERVES TWO FUNCTIONS. IT SETS PINION ANGLE AND IT CONTROLS THE AXLE TWIST, AND THEN THE LOWER CONTROL ARMS LOCATE THE AXLE FORWARD AND BACK, AND ALL OF THESE THINGS WORK TOGETHER TO KEEP THE AXLE EXACTLY WHERE YOU WANT IT AND VERY CONTROLLABLE. THESE COIL OVERS ARE THE BEST FOR WHAT YOU'RE AFTER BECAUSE OF THEIR TUNABILITY. YOU SHOULD BE ABLE TO GET PERFORMANCE AS WELL AS COMFORT

FOR YOUR STREET CAR.

(PAT)>> NEXT TIME WE SEE IT WE'RE PICKING IT UP AND FINAL ASSEMBLY HAPPENS.

(PAT)>> HEY WE'RE BACK HERE AT COFFEY FABRICATION. NOW IT'S BEEN ABOUT A WEEK, AND BOY HAVE THEY DONE A TON OF WORK TO OUR GALAXIE PROJECT. WE CAUGHT THEM AT A GREAT MOMENT BECAUSE THEY'RE JUST

ABOUT REAR TO STUFF THE REAR END UNDER THE CAR AND WELD SOME BRACKETS TO IT. PLUS THEY'VE DONE A LOT OF SLICK FABRICATION TO THE FRONT

AARMS, ALL UNDER THE WATCHFUL EYE OF CHRIS COFFEY.

(CHRIS)>> TODAY WITH THE GALAXY WE WERE SPENDING A LOT OF TIME MEASURING AND MAKING CUTS, AND SLOWLY WORKING UP TO HAVING THE COMPONENTS EXACTLY WHERE WE WANT THEM.

(PAT)>> HE CHOSE CODY BONNETTE TO TAKE THE LEAD, NOT JUST BECAUSE OF HIS SKILLS, BUT ALSO BECAUSE OF HIS PASSION.

(CODY)>> YOU WALK IN AND YOU SEE BEAUTIFUL CARS ALL THE

TIME AND KIND OF BECOME DESENSITIZED. SO RIGHT WHENEVER I SAW THAT CAR I WAS JUST LIKE, WOW, I WOULD LOVE TO WORK ON THAT. AND HOW BIG IS THE TUBE?

(CHRIS)>> IT'S INCH AND FIVEEIGHTS. CODY'S A FRIEND OF MINE WHO'S BEEN HELPING ME OUT FOR ABOUT A YEAR OR SO NOW. HE REALLY JUST STARTED COMING IN ONCE A WEEK MAYBE AND DOING SOME WELDING WHEN I NEEDED SOME HELP. HE'S A PROPERLY TRAINED TIG WELDER. HE DID OIL FIELD EQUIPMENT AND STUFF LIKE THAT, AND HE'S AS GOOD AS YOU GET WITH A TIG TORCH, AND HE'S LEARNING AS WELL, AND HE'S A GREAT FABRICATOR.

(CODY)>> HE'D SAY OKAY, SO FROM THIS POINT TO THIS POINT WE NEED A PIECE AND IT HAS TO BE AT THIS EXACT ANGLE, FOLLOW

THIS LINE, AND LAND HERE, AND BE CUT THE PERFECT LENGTH SO THAT IT FITS JUST RIGHT AND YOU'RE NOT HAVING TO FILL TOO MUCH OF A GAP WITH WELD, AND THAT WAS, IT'S JUST SO IMPORTANT TO HIT THE TARGET. SOMETIMES IT'S A VERY NARROW TARGET BECAUSE PEOPLE'S LIVES REALLY DEPEND ON IT IN THIS CASE.

(PAT)>> IT'S THAT DEDICATION THAT BRINGS US BACK TO COFFEY'S. THE CHASSIS ON THIS PROJECT IS 53 YEARS OLD, STILL SOLID, BUT NOT ENOUGH TO HANDLE THE TURBOCHARGED 347 WE JUST DROPPED IN IT, WHICH IS PRODUCING AT LEAST FOUR TIMES THE HORSEPOWER AND TORQUE THAN THE STOCK 260 FROM THE FACTORY. THE ADDITIONAL STRESS AND TREMENDOUS AMOUNT OF GFORCES THESE MOUNTS WILL NOW ENCOUNTER REQUIRE THEM TO BE EXTREMELY DURABLE. A LOT OF TIME IS SPENT ON FINDING THE EXACT LOCATION AND ANGLES TO MOUNT SOLIDLY TO THE FRAME.

(CHRIS)>> TAKE OUR TIME AND MEASUREMENTS AND GET EVERYTHING RIGHT THE FIRST TIME, AND THEN ONCE IT'S ALL TACKED IN THERE AND MOCKED UP, AND LIKE WE JUST DID NOW AND CHECK THE SUSPENSION TRAVEL AND MAKE SURE NOTHING HITS

ANYTHING ELSE, AND THEN WE START TO WELDING

EVERYTHING COMPLETELY. THE GALAXIE, IT'S GONNA BE A REALLY COOL CAR. UNIQUE FOR SURE, POWERFUL, FAST, SHOULD BE GLUED TO THE GROUND PRETTY WELL TOO WITH ALL THE SUSPENSION WORK WE'RE DOING. WATTS LINK AND TORQUE ARM IN THE BACK, AND COIL OVERS UP FRONT, AND REALLY BIG BRAKES ALL THE WAY AROUND, AND AS MUCH TIRE AS WE CAN GET UNDER IT, AND IT'S GONNA BE A NICE CAR.

(MIKE)>> NOW IT'S TIME FOR US TO LET CHRIS AND CODY DO WHAT THEY DO BEST, FINISH UP THE FABRICATION ON THIS OLD GALAXIE. NOW NEXT TIME YOU SEE IT, IT'S GONNA BE BACK IN OUR SHOP, BUT DON'T WORRY. WE'RE GONNA PULL ALL THE SUSPENSION BACK APART SO YOU CAN SEE HOW IT WAS MADE AND HOW IT GOES BACK TOGETHER.

(PAT)>> IT'S REALLY GONNA UPDATE THIS CAR AND BRING IT INTO THE FUTURE. IT'S GONNA HANDLE LIKE NO OTHER GALAXIE I'VE EVER SEEN.

(MIKE)>> EVERYTHING IS BACK AT THE SHOP, AND WE'RE READY FOR FINAL ASSEMBLY. WE'RE STARTING WITH THE REAR SUSPENSION. CHRIS ALSTON'S CHASSIS WORKS IS A LEADER IN SUSPENSION DESIGN AND MANUFACTURING. THIS IS THEIR UNIVERSAL FIT TORQUE ARM SYSTEM THAT POSITIONS THE CURRIE NINE INCH UNDER THE GALAXIE, AND CAN BE ADAPTED TO PRETTY MUCH ANY VEHICLE. TO ELIMINATE DELAYED RESISTANCE IN THE ANTIROLL SYSTEM A CHASSIS WORKS SPLINED IN TUBULAR ANTIROLL BAR IS INSTALLED ON THE HOUSING. IT'S A THREE QUARTER INCH ALLOY STEEL BENT TUBE DESIGN. NOW IT CLEARS FAB NINE AND OEM CENTER SECTIONS. BILLET PIVOT SOCKETS THREAD INTO THE LOWER BRACKET AND ALLOW THE BAR TO ROTATE SMOOTHLY IN A PLAY FREE JOINT.

(PAT)>> THE TORQUE ARM COMPLETELY ELIMINATES AXLE WIND UP AND BUSHING DEFLECTION. IT GIVES THE VEHICLE INSTANT THROTTLE AND BREAKING RESPONSE. CHASSIS WORKS OFFERS THEM IN THREE DIFFERENT LENGTHS TO ACCOMMODATE DESIRED SUSPENSION GEOMETRY.

(MIKE)>> FRESHLY PAINTED, DON'T DING IT UP.

(PAT)>> I'M VERY CAREFUL, CAN'T YOU TELL.

(MIKE)>> THE TORQUE ARM CROSS MEMBER IS WHAT THE FRONT OF THE TORQUE ARM ATTACHES TO. THIS ALSO PULLS DOUBLE DUTY AS THE TRANSMISSION CROSS MEMBER. ITS DESIGN AND MOUNTING POINTS ALSO WORK TO STIFFEN THE CAR'S FRAME. WITH THE REAR POSITIONED, THE CAR IS LOWERED DOWN. WE'LL START THE INSTALL BY LOCATING THE TUBULAR GLINK ARMS IN THE FRAME BRACKETS. THEY'RE ADJUSTABLE, EXTERNALLY GREASABLE, AND ARE THE ULTIMATE PERFORMANCE LINK FOR STREET AND TRACK DRIVEN APPLICATIONS. THE TORQUE ARM IS NOW CONNECTED TO THE THREE HOLE FROM MOUNT, WHICH PROVIDES ADDITIONAL PINION ANGLE ADJUSTMENTS.

THESE LINKS CONNECT THE ANTIROLL BAR TO THE CHASSIS.

(PAT)>> CHASSIS WORKS ALSO SUPPLIED THESE AWESOME VARISHOCK QUICK SET FOUR REMOTE RESERVOIR COIL OVERS. THEY ALLOW SEPARATE ADJUSTMENTS FOR BUMP AND REBOUND. EACH SHOCK HAS 16 DIFFERENT POSITIONS FOR REBOUND, AND THE SPRING/SHOCK COMBO GIVES US FIVE INCHES OF TRAVEL.

(MIKE)>> THE TORQUE ARM AND TUBULAR GLINK ARMS KEEP THE

AXLE FROM WRAPPING, BUT TO KEEP IT PERFECTLY CENTERED IN THE CAR DURING SUSPENSION TRAVEL WE'RE USING A WATTS LINK. THIS BILLET PIVOT ASSEMBLY IS ATTACHED TO THE REAR HOUSING. THEN 4130 TUBULAR STEEL LINKS ATTACH TO IT, AND MAKE THE FINAL CONNECTION TO THE LASER CUT FRAME BRACKETS THAT WERE WELDED IN AT COFFEY'S.

(PAT)>> A BIG CAR WITH A WHOLE LOT OF POWER NEEDS A BRAKE SYSTEM THAT CAN HANDLE ANY SITUATION, FROM A HARD DAY AT THE ROAD COURSE TO HIGH TRAP SPEEDS AT THE DRAG STRIP. BAER'S 14 INCH EXTREME PLUS BRAKE SYSTEM UTILIZE A MONO BLOCK SIX PISTON CALIPER AND A TWO PIECE DRILLED AND SLOTTED ZINC PLATED ROTOR, AND INSTALLING THEM IS SUPER SIMPLE. BILLET CALIPER BRACKETS BOLT TO THE BACKING PLATE USING

THE SUPPLIED FASTENERS. SPACERS SLIDE ON, AND THE CALIPER IS LOCATED ON THE BRACKET STUDS AND TIGHTENED DOWN. STEEL BRAIDED BRAKE LINES FROM CROWN PERFORMANCE GO ON NEXT. A BRACKET AND CLAMP SUPPLIED BY BAER LOCATE IT ON THE HOUSING. UP FRONT IS THE SAME SETUP.

THE SYSTEM IS DESIGNED TO WORK WITH THE GALAXIE SPINDLES, BUT WE DO HAVE TO ENLARGE A COUPLE OF HOLES TO ACCOMMODATE THE LARGER FASTENERS. THE SPINDLES ARE HARD, SO USE PLENTY OF LUBE WHEN DRILLING. NOW THE BASE BRACKET CAN BE INSTALLED WITH HALF INCH HARDWARE. THE INTERMEDIATE, OR CALIPER, BRACKET GOES ON NEXT. THIS HUB IS BILLET ALUMINUM AND COMES WITH PREPACKED SYNTHETIC GREASED BEARINGS. IT SLIDES ON THE SPINDLE. THEN THE CASTLE NUT IS INSTALLED AND TIGHTENED TO AROUND 10 POUND FEET. NOW LOOSEN THE NUT AND RETIGHTEN AS YOU TURN THE HUB.

THIS PROCESS SHOULD BE REPEATED A FEW TIMES. THE FINAL STEP IS TO REMOVE PLAY AND TIGHTEN APPROXIMATELY A 16TH OF A TURN TO GIVE THE BEARING A SMALL

AMOUNT OF PRELOAD.

FINALLY THE COTTER PIN IS PUT IN PLACE AND THE SUPPLIED DUST COVER IS TIGHTENED DOWN.

(MIKE)>> THE LAST COMPONENT IN THIS KILLER BRAKE SYSTEM IS BAER'S REMASTER BILLET ALUMINUM MASTER CYLINDER. IT'S A DIRECT REPLACEMENT AND AVAILABLE WITH A FORD, CHEVY, AND DODGE BOLT PATTERN. A 15/16THS, ONE INCH, AND INCH AND AN EIGHTH BORE SIZE IS AVAILABLE FOR THAT OPTIMUM BALANCE IN PRESSURE AND VOLUME. NOW MOUNTED TO THE BOTTOM IS AN OPTIONAL ADJUSTABLE PROPORTIONING VALVE. IT ATTACHES DIRECTLY TO THE FIREWALL. ARP BOLTS WILL SECURE IT.

WE'RE NOT GOING TO BORE YOU WITH RUNNING ALL THE BRAKE LINES. WE'LL TAKE CARE OF THAT LATER ON. NOW IT'S TIME TO MOVE ON TO THE FUEL SYSTEM. NOW WE MOUNTED A SUMMIT RACING 15 GALLON ALUMINUM FUEL CELL BACK HERE IN THE TRUNK. IT'S SETUP FOR EFI THAT REQUIRES A RETURN LINE BACK TO THE TANK. THEY'RE ALL DASH EIGHT IN SIZE. IT ALSO COMES WITH A SENDING UNIT, AND WE UPGRADED THE

FILLER WITH A SCREW ON CAP FROM EARL'S PLUMBING.

(PAT)>> COMPLIMENTING THE HOLLEY EFI SYSTEM WE'RE RUNNING ON THE CAR IS THEIR NEW VR ONE BRUSHLESS FUEL PUMP AND CONTROLLER. IT WILL WORK IN BOTH CARBURETED AND EFI APPLICATIONS, AND MUST BE USED WITH A RETURN STYLE REGULATOR. IT WILL SUPPORT UP TO 2,150 HORSEPOWER IN EFI APPLICATIONS, AND COMES WITH THIS TWO STEP CONTROLLER THAT WILL ALLOW THE FUEL PUMP TO RUN AT ONE OF TWO DIFFERENT SPEEDS.

(MIKE)>> THE TANK HAS TWO DASH EIGHT FEED FITTINGS THAT

GO TO AN EARL'S YBLOCK.

THE OUTLET IS DASH 10 AND GOES TO A HOLLEY BILLET ALUMINUM 100 MICRON PREPUMP FILTER. FROM IT THE DASH 10 LINE CONTINUES THROUGH THE FRAME RAIL. THIS PUMP CAN BE FULLY SUBMERGED IN A FUEL CELL OR CHASSIS MOUNTED LIKE THIS. NOW IT CAN MAINTAIN PRESSURES UP TO 130 PSI AND FLOW UP TO 335 GALLONS PER HOUR, MAKING IT GREAT FOR A FORCED INDUCTION SETUP LIKE OURS. THE CONTROLLER IS FULLY SEALED AND WILL MOUNT CLOSE TO THE PUMP. FROM THE PUMP THIS LINE RUNS TO A 10 MICRON POST FILTER, AND THIS LINE RUNS UP TO THE ENGINE BAY. WE'LL BE RIGHT BACK.

(MIKE)>> WE'RE BACK AND CONTINUING ON WITH THE FUEL SYSTEM. NOW TO REGULATE THE FUEL PRESSURE WE'RE USING ONE OF HOLLEY'S BRAND NEW VR SERIES FUEL PRESSURE REGULATORS. NOW THESE ARE DESIGNED TO BE RAN WITH THEIR NEW BRUSHLESS SERIES PUMPS. THEY'RE AVAILABLE IN CARBURETED AND EFI APPLICATIONS. NOW FOR EFI THEY'RE ADJUSTABLE FROM 40 ALL THE WAY UP TO 100 PSI. NOW THEY'RE MADE OUT OF 60-61 TSIX BILLET ALUMINUM AND AVAILABLE IN TWO AND FOUR PORT CONFIGURATIONS. HOLLEY SAYS THEY'LL SUPPORT UP TO 3,000 HORSEPOWER. I'M MOUNTING IT ON THE FIREWALL CLOSE TO THE FUEL RAILS SO WE CAN MAKE SHORT RUNS WITH THE LINES.

THE FEED LINE GOES DIRECTLY TO THE FUEL RAIL SO THE INJECTORS RECEIVE FULL PUMP PRESSURE AND NOT REGULATED. NOW A LINE COMES OFF THE OTHER RAIL AND GOES TO THE REGULATOR. TRY TO REGULATE PRESSURE AFTER THE RAILS ANY TIME YOU CAN. FINALLY A RETURN LINE IS RAN FROM THE REGULATOR ALL THE WAY BACK TO THE TANK.

(PAT)>> WITH OUR FUEL CELL IN AND MOUNTED SOLID IT'S TIME TO PUT IN OUR SEALED BATTERY BOX KIT FROM SUMMIT RACING. IT COMES WITH ALL THE MOUNTING HARDWARE AND CABLING TO PUT IT ANYWHERE YOU WANT IN THE VEHICLE, AND FOR WEIGHT TRANSFER PURPOSES WE'RE PUTTING IT IN THE PASSENGER SIDE REAR. I PREDRILLED THE HOLES AND DROPPED IN THE STUDS. AN OPTIMA RED TOP AGM BATTERY WILL GO IN FOR TROUBLE FREE SERVICE. ALONG WITH THE SUSPENSION WORK, ANOTHER BIG UNDERTAKING TOOK PLACE INSIDE THE CAR HERE WHEN IT WAS AT COFFEY'S, AND THIS IS WHAT LED UP TO IT. THE MAGNUM TRANSMISSION IS MUCH LARGER THAN THE OLD TOP LOADER THAT WAS IN THE CAR. DURING MOCK UP WE REALIZED THE TUNNEL NEEDED SOME MODIFICATIONS. SO SEVERAL MEASUREMENTS WERE TAKEN TO GET AN IDEA OF WHERE THE CLEARANCE NEEDED TO BE.

INSTEAD OF CUTTING SOME GAPING HOLES AND BEATING ON IT WITH A

HAMMER, THE DECISION WAS MADE TO REMAKE BOTH THE TRANS TUNNEL AND DRIVESHAFT TUNNEL OF THE CAR. CHRIS IS A HIGHLY SKILLED METAL WORKER, AND THIS BEEFY TRANS TUNNEL SHOWS HIS EXPERTISE. PRECISE BENDING AND BEAD ROLLING NOW ONLY GAVE IT GREAT EYE APPEAL, BUT ALSO STRUCTURAL INTEGRITY. THE DRIVESHAFT TUNNEL IS MADE FROM 18 GAUGE SHEET STEEL

THAT WAS PRECISELY SHAPED ON A PRESS BREAK. THIS PROCESS AND MATERIAL CHOICE MAKE THIS STRONGER THAN THE ORIGINAL. TO GO THROUGH THE GEARS AMERICAN POWERTRAIN SENT US THIS MULTI POSITION ADAPTER SO THE SHIFTER HANDLE CAN BE POSITIONED WHERE THE DRIVER IS MOST COMFORTABLE. THEIR 10 INCH POLISHED STAINLESS STEEL SHIFTER HANDLE REMINDS US OF THE ONES IN THE OLD NASCAR RACE CARS OF YESTERYEAR. TOPPING IT ALL OFF IS AMERICAN POWERTRAIN'S SIGNATURE SHIFT KNOB WITH THE SHIFT PATTERN OF THIS BEEFY MAGNUM.

(MIKE)>> I HATE TO SAY IT BUT WE'VE RAN OUT OF TIME TO

ADVANCE THE GALAXIE ANY FARTHER TODAY.

NOW WE MADE GREAT PROGRESS BY GETTING ALL THE SUSPENSION BOLTED UP, AS WELL AS THOSE MASSIVE BAER BRAKES INSTALLED. PLUS SEVERAL OTHER ODDS AND ENDS LIKE THE BATTERY BOX, SHIFTER, AND FUEL SYSTEM ALL COMPLETED.

(PAT)>> AND WE STILL HAVE PLENTY TO DO, LIKE THE COLD

SIDE OF THE TURBO SYSTEM, WHEELS AND TIRES, SOME INTERIOR STUFF, AND THE REST OF THE HOLLEY EFI. NOW WE HAVE TO GIVE A HUGE THANK YOU TO CHRIS AT COFFEY FABRICATION AND RACE PREP, AND CHRIS ALSTON'S CHASSIS WORKS FOR HELPING US MAKE THIS ARGUABLE ONE OF THE BEST

HANDLING GALAXIES ON THE PLANET.

(MIKE)>> THE HIGH PERFORMANCE AFTERMARKET WORLD HAS ALMOST UNLIMITED AMOUNTS OF GO FAST PARTS FOR YOUR ENGINE PROJECT, NO MATTER THE BRAND YOU FAVOR. NOW THIS TECH TIP IS GONNA GO OVER THE BASIC GUIDELINES FOR CHOOSING THE CORRECT SIZE CYLINDER HEAD FOR YOUR APPLICATION. NOW WE GET A LOT OF QUESTIONS ABOUT THIS, SO LET'S GET RIGHT TO IT.

(PAT)>> BACK IN THE DAY THE ONLY WAY TO GET A GOOD FLOWING CYLINDER HEAD FOR YOUR RACE OR STREET BULLET WAS THE HAVE IT HAND PORTED AT A PROFESSIONAL SHOP, AND THAT WAS COSTLY IN BOTH TIME AND MONEY, BUT WITH FIVE AXIS CNC PORTING EQUIPMENT BEING THE NEW INDUSTRY STANDARD, GREAT FLOWING CYLINDER HEADS ARE CRANKED OUT MORE RAPIDLY AND ACCURATELY THAN EVER BEFORE.

(MIKE)>> WHEN WE REFER TO THE SIZING OF THE HEAD, WHAT WE'RE TALKING ABOUT IS THE VOLUME OF THE INTAKE AND THE EXHAUST PORTS, AND THAT IS EXPRESSED IN CC'S. NOW IT'S A PHYSICAL MEASUREMENT OF THE ACTUAL PORT SIZE.

ALSO TAKEN INTO CONSIDERATION ARE THE VALVE SIZES, AS WELL AS THE COMBUSTION CHAMBER VOLUME. NOW THESE ALL DIRECTLY EFFECT THE OUTPUT OF THE ENGINE.

(PAT)>> COVER SOME GENERAL INTAKE PORT SIZING FOR STOCK, STREET AND STRIP, ALL THE WAY UP TO RACE APPLICATIONS, AND WE'LL START BY GOING OVER SOME STOCK STUFF IN BOTH

SMALL BLOCK AND BIG BLOCK APPLICATIONS. FOR ENGINES THAT ARE STOCK OR HAVE BEEN SLIGHTLY MODIFIED, LIKE WITH A CAM SWAP OR AN INTAKE AND CARB, 150cc TO 170cc ON THE INTAKE RUNNER SIDE FOR ENGINES COVERING 300 TO 400 CUBIC INCHES. ON THE BIG BLOCK SIDE 250cc TO 290cc COVERS 400 TO 500 CUBIC INCHES WITH SIMILAR MODIFICATIONS. THE STREET AND STRIP CATEGORY INCLUDES ENGINES WITH MORE EXTENSIVE MODIFICATIONS, LIKE INCREASED COMPRESSION AND HEADS THAT WILL FLOW MORE IN THIS RANGE, AND THEY WILL BE

FROM 180cc TO 220cc ON THE INTAKE SIDE, AND THAT COVERS ENGINES UP TO 440 CUBIC INCHES. ON THE BIG BLOCK SIDE 280cc TO 340cc, AND THAT GOES ALL THE WAY UP TO 500 INCHES. NOW THESE HEADS WILL HAVE BIGGER VALVES, MAYBE EVEN A TIGHTER CHAMBER, AND THE HEADS WILL FLOW MUCH BETTER. IN A RACE APPLICATION THE SKY IS THE LIMIT, AND THIS IS A FULLY BUILT RACE ENGINE WITH CUSTOM PISTONS, CAM SHAFT,

AND EVERYTHING FINELY TUNED. 230cc TO 280cc ON ENGINES UP TO 470 CUBIC INCHES. NOW THAT COULD ACTUALLY BE LARGER IF IT HAS A HIGHER OPERATING RANGE. ON THE BIG BLOCK SIDE, 360cc TO 470cc ON ENGINES UP TO 650 CUBIC INCHES OR LARGER, AND THAT'S THE EXTREME SIDE OF THE SCALE. NOW KEEP IN MIND, RACE ENGINE'S PORT SIZING IS COMPLETELY DEPENDENT ON ITS RPM RANGE AND ITS APPLICATION, AND THAT DOESN'T TAKE INTO ACCOUNT ANY FLOW NUMBERS, WHICH IS A COMPLETELY DIFFERENT ANIMAL THAT WE'LL GET INTO AT A DIFFERENT TIME.

(MIKE)>> DON'T FORGET, YOU CAN CHECK OUT ALL OF OUR PAST BUILDS AND PROJECTS PER EPISODE BY LOGGING ON TO POWERNATION TV DOT COM. NOW WE'LL SEE YOU NEXT TIME WHEN WE BRING

YOU MORE GREAT TECH.
