Have a competent shop do a blown LS conversion, they will also replace your gears and transmission.

i already got my guy for my trans rebuild... other than that motor will be done by me an tuned on a dyno an the gears too ill be doin... im a firm believer if u want it done right u gotta do it urself... i went to school for high performace engine buildin an certified by dyno jet... so i gotta put my 20G's to good use...lol
