Well.....It really depends on alot of variables. It's hard to beat a TH400 for durability. A well built TH350 will do the job, too, with the benefit of a lower first gear. I had a Powerglide in my 64 that was awesome, but I also had the torque #'s to pull it off.baja said:what kind of tranny would u suggest for a 64 GTO with a crossbred 383 motor in it that will be dragging the 1/4?
Well.......fractionally so. Not much. But I agree, if it were me, and I wasn't making 5-600 hp+, I'd use the TH350.GTODEALER said:I heard it actually takes more power to "run" the larger TH400 tranny,
