[67gtospud]

I’m finishing up the engine for my 67 GTO now. It’s a street car, weekend cruiser and occasionally take to work when the weather permits. The engine build is as follows:

1968 428 block out of a Bonneville.
Bored .030” with a total of 432 cubic inches
Factory modular crank
Billet 4-bolt main caps w/arp studs
Crank scraper and baffled oil pan
Scat H beam connecting rods w/ arp 2000 bolts
Icon forged pistons w/ 10cc dish; pistons .010” in the hole.
Lunati 20510713 hydraulic roller cam (243/251@.050” .618/.622 lift w/ 1.65 rockers)
Johnson Hylift short travel hydraulic roller lifters (.058” total plunger travel)
Harland Sharp 1.65 full roller rockers
Butler/Smith Brothers 5/16”x.116” pushrods
Edelbrock RPM round port heads. (Out of the box setup by Butler Performance)
Prw fabricated valve covers
Offenhauser low rise 2-4 intake manifold
Factory distributor with Pertronix igniter 2 and flamethrower coil; distributor setup by advanced distributors
2-Edelbrock 1405 (500cfm) carbs on progressive linkage
Centerforce billet flywheel w/ McLeod street extreme clutch

I’ll be putting this on the run stand in a week or 2 then mating the Super T-10 to the engine and re-installing it. Late spring, after a thorough break in, I plan to put the car on a chassis dyno for my own pleasure. My goal is around 500 wheel. I’m aware I can’t stick it to the ground with my current 255 tires and i don’t think my bop 8.2 would handle the power if I could stick it anyways. An aftermarket 12 bolt or 9 inch is likely my next upgrade in the future.
