I have a brand new Fidanza aluminum flywheel for an LS1 for sale. It should fit any Gen III small block (up to 05.)
I recently purchased a 1990 Acura Integra LS with 225,000+ miles on it. It is in really rough shape, but I find it a steal for the $200. It needs to make it through the lovely Wisconsin winter then I may try to use it for Chump Car / 24 Hours of Lemons.
