I am doing the LS1 swap after two years of car shows, racing, reading and researching. You would be amazed at what guys are swapping LSX into, but like VinhZXT stated it is cost, dealing with wires and a pcm. However, Edelbrock has the intake/module/cam set-up to run a carb on a LSX motor and some new stuff coming out in 2007 for LSX and LT engines.
