What Robert said. I believe the piston starts getting so short in the 500 inch B block, that you get into longevity problems. Thrust forces, piston slap, etc. Kinda depends on what your goals for the engine are.



This is good to know, longevity is one of my main concerns. I want to build a really stout street motor that may go into either a B or C body. This great info guys, thanks a lot!
