stroke bore question? What would be the benefits of using an iron block bored 60 over and a 3.27 crank (4.8 engine) and 6.2 length rods, besides high rpm's? Or not overboring the block, leaving it with stock bore with these crank and rods.

Re: stroke bore question? Overboring the block will yield more cubic inches of displacement which equals more rwhp. Going with a smaller stroke crank will allow the motor to rev higher since there will be less angular momentum. With a 3.27" stroke crank, I am pretty sure 6.2 rods would be incorrect.
