ok the 350 in my sub is gettin TIRED! i'm gonna need a new engine soon. i'm actually just thinking about boring it out .030 over and putting in a mild roller cam and roller rockers. how much would it cost to have it bored out? before you give me all kinds of suggestions about different engines, i want you to know i have already thought about crate motors (ht383, base 350 HO, ramjet 350)and converting mine to a 383 and being a poor colledge kid it's out of the question.
