wondering if anyone has any feedback on the T56 tranny. I currently have a T5 behind a 300+hp 289 but I am adding a paxton so I don't think it will hold up. Any transmission(manual) suggestions/recommendations?
I may be mistaken, but I don't think a T56 will bolt up to a 289. If you want the ultimate in strength for your motor, then a good old Toploader is what you want. If you want the OD gears too, then a Tremec 3550 is next in terms of strength.
I'd consider the richmond sir, from what I have heard it is VERY strong, it is supposed to be a drop in replacement for a T-5 and is a 6-spd, single OD. (well the one I'm thinking of anyhow. Look at gp001's setup.
