Syst, you should be easily under 3k. I'm also curious to see the weight distribution with the LS1.
And for stripping the car, I was able to get my brother's supra down to 3k lbs by just removing stuff. Getting rid of extra engine stuff, everything inside that wasn't needed, etc. But I also took out a little more than most people would. Weight distribution wasn't too bad, I think it was 54-55% front, don't remember, it's written down somewhere though. But the battery was also moved to the inside and I did remove a lot of engine parts as well.
