Re: 572 questions / Help
I would think the intended rpm of the motor should determine which way you go.
I would go the "big inch - low rpm" route. I would build a 540-598 and never turn it over 6000 rpm. The block could be the cheaper blueprint block and all the stock parts will fit.
Valvetrain will be cheaper. Not as easy to destroy parts with a low rpm torquer.
Just an all-around more fun car.
Build a sleeper and put 396- 350 hp stickers on it. No wild cams- just killer torque.
