i paid $350 for a shop to do it the first time. a month later needed a re-stall so i did it myself and wasn't too bad. if you can get a friend to help, that would speed things up tremendously

 

no XP in okc did a cam swap stall install tune etc and he wouldnt install the stall unless i had a tranny cooler installed which added another 200 to my bill i didnt feel like working on the car in my cold *** garage anyways tho so 2k well spent IMO car made 400 rwhp w/4L60e cam only with a 90/90 combo stock injectors stock maf etc
