New to this site...wish I would have found it earlier. I have an 84 g-body project about to be finished for its test drive...CANT WAIT. Its a 1984 Grand National...I purchased it as a roller no interior. Since then I have installed a 406 sbc that should put down around 450-500 rwhp. It has a built turbo 350 with a TSI 3800 converter, the stock GN rear was updated to a EZ locker rear with new 4:10 gears. I hoping for some 11 second runs.
