Just been reading a lot on some topics on GP Pontiac, I have a 84 with a 69 400 H O in it. Bore 60 over with a comps cam 501 1.65 roller rockers 2 stage oil system. Turbo 400 with 2500 stall , all I have left is the rear end it's stock having some traction problems . LOL this is my first G-body car I built, I have a 1970 gt 37 Tempest had it for 25 years, replaced the engine with a RAM AIR 3 runs a 12.59 all stock . I know some of you g body gear heads can help with my traction problem.
