Toyota has a totally bitchin 5 speed that has a really high torque rating, made by aisin. It was used in turbo Supras. That one I can see, for a hot V8, but with a stovebolt six the S10 T-5 seems like the hot ticket. I'm looking for the Supra trans for my '66 chevelle, adavanced adapters make the plate for it. It has like a 450 lbs torque rating, and nice ratios for a hot rod!
