ls3 upgrade
got an ls3 6speed with lg longtubes, npp exhaust, and K&N CAI. Heads and cam are next on the list. I've been hearing about going towards porting heads as the best choice. What do you guys recommed? what will boost up more ponies to the vette?

Free bump. I read in a thread a while ago that a car with the g6x3 and their heads dyno'd 530 rwhp... I would love for them to chime in. TSP has had great success with their 231/236 ls3 cam - they also had a H/C combo using l92 head castings done by PRC.

It's also best to know what you intend to do with the car, before mods can be considered an improvement. It starts with answering questions, like the one LS1LT1 asked. "Manual or automatic?" it does make a difference when offering recommendations.
