i want to build a 351w and push it to 700hp. i have a 72 block and im planing on putting h beams with dished pistons, i also want to convert it to a roller cam and use ported stock heads for now with head studs and my turbo kit for my 5.0 will the stock pistons and crank hold up i heard that they are stronger than the blocks but i want to make sure before i build this motor
