I’m sure you’ve already researched the differences between a corvette T56 and all other T56s (different input design - not mounting directly to the engine; and different output housing design - mounting directly to the differential instead of to a driveshaft), so I’ll just give testament to my 6 speed for the sake of it being a 6 speed.

I put a T56 from a 96 LT1 Camaro behind my tubo’d 454 and couldn’t be happier. The low end torque from the motor allows me to run in 5th as low as about 30 mph, and in 6th at about 55 mph. The tires will blow off if I get into it in those gears at those speeds, but that’s what downshifting is for. 1st-4th gears are pretty similar to a Muncie spread, 5th and 6th give the truck legs to run and run and run. My sweet spot for cruising on the highway is 6th gear, 75mph, ~1700 rpm. 4.11 rear end, 275/55/20 street tires.


It’s an awesome feeling when somebody comes up on me at highway speed and I drop 3 gears and run next to them. I usually get a shocked look, then row the boat and leave them behind.
