Thanks for the responses guys. We always want huge power lol but I really hope this motor will have a nice tq curve and produce good avg power thru the range we will be running it.
Theres alot of room for improvement no doubt. With some port work to the intake and heads and some more compression but I think it will be pretty competitive against the crate motors like it is.
