1977 Chevy Stepside 3000lb 342 gears 700r4 350 with Vortec Heads 64cc with 1.94 intake and 1.50 exhaust valves.These also have .500 lift springs,3/8 screw in rocker studs,Comp long slot 1.5 rocker arms with poly locks,and Isky guide plates. No cam yet or intake I can use 8 bolt or twelve on these heads. Horsepower the most without blowing it up 650 Edelbrock new carb. I will boost the compression up if it helps to acheive higher ponies. This is an older block 1969 010 two bolt. It has the original camel humps on it now. Choices comments and suggestions welcome. Use it on the track why not its only fun.

Thanks Roy
