I just bought a new LS2 out of a TBSS with a 100 miles on it for my 09 tahoe. I am debating if its worth changing over to LS3/L92 top end (heads and intake) or just leave the LS2 alone. I am debating on doing a supercharger when I do the swap. If I do the supercharger I am going to leave the motor alone, just havent made my mind up. Are there any worthwhile gains with LS3/L92 top end?
