Preparing for More HP
Upgrading the rear end is not a bad idea. Although I chose to upgrade the motor until the rear end breaks and so far I've been lucky. So it's up to you.
Best thing I can say to you is to not to wimp out when you buy parts, or else you'll be buying them twice. For instance, I bought 1 3/4" headers, but now am looking at 1 7/8". I have a 98 so it came with the LS1 intake and so I got a LS6 intake, but now I am looking at FAST 90/92 intakes. I bought unported 243's, but then immediately bought cnc ported 243's before even installing them... I think you get the point. Going that way is an expensive route. Buy it right the first time and save in the long run.
