What parts do you have?
Rebuilt 318 heads to stock specs, carb, intake, distributor, ignition, headers, cam that's sounding like its too small and a block that needs to get refreshed
What is the budget?
Kinda don't have one but I'm not taking this truck too seriously either
What is the goal?
Fun for me, a muscle truck for the boy to learn hot rodding on. Street manners.
What year engine?
74
If you are buying pistons,shoot for 9.8 to 10.2.
Copy. will go for the 10:1's
Cam is too small,look for a 480ish,torque cam.
Advance the cam 2 to 4 degrees.
Sounds good.
.028-.038 head gasket,aluminum heads a plus,or use later 302 heads,360 heads.
