maybe 550 to 580 hp. Its just a pump gas motor street car. When you switched to the 1.96 what did you loose in 60' and et? What rear gear and tire were you running? I really want to get this thing into the 9's

I ran a 355" sbc in a 2860# chevy II with a 1.76 glide 5.67 rear gear. Car went a best of 1.33 60' @ 9.86 and consistent 9.90's @132mph at 8200 rpm in cool weather. I put a 2.03 low gear and 5.43 rear gear. 60' times dropped to 1.30-1.29 and ran basically the same E.T. and mph at 7900 rpm. You will have more rpm drop at gear change with the lower gear ratio. Car has a 8" 5800 convertor and a 15" x 33" 105" roll out. I leave with the trans brake at 4200 rpm. The car was more consistent with the 2.03 low gear due to being able to transfer the weight better, and a whole lot more fun to drive! The 2.03 broke after about 350 runs. I put the good old reliable 1.76 back in for now! Hope this helps.

When you guys say the 1.76 gear set, is it a stock used gm gear set with the stock carrier and out put shaft? One option I'm thinking about is a 1.80 straight cut gear by transmission specialties in P.A. The whole tranny is $1600 PL-2500

I would go with the 1.98.... now then in a "stocker" we picked up .15 going from a 1.82 to a 2.08!
