I have a 3.11 first gear sag 4 speed with a gm 26lb 10.5 153 tooth flywheel with a stock replacement clutch. My engine is a 4.060 350 with 461 d humps 238/244 @.050 dur 502/516 lift hyd cam edlebrock rpm intake 750 holley vac sec. I haven't figured what rear gear to run yet but I have a stock posi and just 15x8 street tires and I'm not finished with my Nova but I'm making it as light as I can and I have a Summit Racing universal four speed shifter. I know you can't just go stupid with these trans but how far can I push it, what gear, what fluid and how much just might help it? I'm not going to the strip because a 3000 clutch dump and I would be afoot, but I will drive through some turns you know down shift and up shift you know, drive it. So anyone that has had experience with these let me know how I can get the most performace on a moderate budget. I have a friend that ran one and drag raced it in a 55 Bel-Air with a hot 327 and it is still in one piece.
