1975 chevy 454 2 bolt main bored .60 over, 468 cid. Cast heads, peanut port. Internally balanced, completely rebuilt, almost all ARP bolts. Manley stainless steel valves, comp cam, with comp springs, comp magnum rockers 1.72 ratio, hydraulic lifters, comp pushrods, proform timing gears, fuel pump blockoff, edelbrock dual plane intake, aluminum tall valve covers. Built this engine and just changed direction. Cons of the build, harmonic balancer isnt completely back all the way, so pulleys dont line up and throws belts. First 3/4” threads in crank stripped from improper installation of balancer, but still plenty of threads left. I have receipts of all the parts, and video of it running. Just need to get rid of the engine. Ask any questions and ill answer as much as i can. $2500 obo
