1999 LS 3.1 L
There isn't much you can do to get serious power out of it. The 3.1 was designed to be an economical engine, not base platform for power. Your best bet would be to swap for a 3800 or 3800 Supercharged. You can get good info at www.l67swap.com
Don't bet me wrong, you can mod a 3.1, but $ for $ it isn't worth it compared to the swap.
