I am thinking more seriously about my transmission choice for my build. It' a 70 Electra with 2.93 rear gears. The motor will push about 600 hp/torque at the crank and I'm curious to know what trans you guys would use. The motor will have a roller cam similar to a 413 grind and thinking about a 2000-2500 stall converter. Overdrive would be almost useless even at interstate speed. Th350 or th400 is what I'm thinking about. I like the 350 because of less parasitic loss, but would it hold up to 600ft lbs in a big electra with 2.93 gears?
