Im doing both. The motor in my current project is using both front and rear motor plates to mount it into the A/M frame. I will swap between the 4L80E and T-56, and with the motor supported on both ends, tranny swaps get real easy under the lift. Im betting I could do it in a couple of hours by myself.
I want the T-56 because its a ton of fun to manually shift a hi HP car (Procharged 542ci pump gas combo....approx 900 HP). But, I will also be making some serious 1/4 mile passes, and want the increased performance and consistency that the auto will have. Frame goes into the race car shop on Jan 3 for the 4-link and watts setup install. The minitub on the body is also underway to make room for the rear tires (the rear seat is going to be pretty narrow).
Question for someone who knows the answer to this. We have to cut the floor out of the car to get it onto the A/M frame. Then, with the drivetrain installed, put a floor back in leaving the required clearance in the tunnel. We would like to use the larger (physically) of the 2 tranny setups to do this. One will be the 4L85E and the other will be the T-56 on a McLeod modular bellhousing.
Which setup is the larger one?
