Looking for a little more power out of a 318

I have a comp XE 284, thing has a mean lope in a 318, I can tell you.... but rumblefish has some good advice. Comp XE262 or XE268 would be really good choices for you. 262 if you want good power with really good street ability, 268 if you want to trade a little streetability for some top end power and and little more rough idle.
