X-TECH MAN is right on, for the street it's hard to beat stroker motors that remain pump gas friendly. Correct clearances, file your ring end gaps, etc. are essential and let a good shop bore/hone your block. Also, given the tighter convertors (you do NOT want a "stocker" convertor on the street any more than you want 5:13's) cam selection is absolutely critical. Don't catalog shop, talk to one of the reputable cam makers and tailor the cam to your combo. Finally, get all the weight out of your car that's practical, it pays dividends in every area of car performance.

P.S. Crate motors are a pretty good deal but again selection is key and cubic inches rule. If you decide to go crate motor then start a new thread soliciting feedback, there is a wealth of knowledge on this forum. Also helpful to indicate your current car/motor. Every make has it's own following.
