My question is, how strong are the internals of a 1972 big block 402? im kind of hoping i can reuse the cast iron crank and connecting rods. I have heard the connecting rods are pretty good from a 72 402 truck. I want about 500 hp b/c its gonna be a street/ import killer. ill probally be looking at the rpm package through edelbrock. 454 oval heads, and all the good stuff to make that set up work. Money dont grow on trees so thats why im interested on reusing as many parts as i can without worrying about giant holes in my block from throwing a rod or something.
