i dont know its all really confusing if i end up doing a ls vtec swap i will find a bad ass shop for it weither i have to drive to s.a., houston, or even dfw area i will and i will get a hotel room till the work is done, but im starting to like the crower 403's with a turbo, the only thing is that i dont want a super rough idle or any hesitation off the line , and for the price of cams id want alittle more then 15- 18 hp like they say, with the crower 403's and the 404's where does the most power get put in the lower, mid, or upper rpm's? my ls tranny seriously needs some power in the uppers esp 5th.....
