Flywheel for T56 swap
I have a 1977 350 motor in a 91 Camaro. I am swapping the 700R4 for a 1997 T56 transmission, but I am confused about what type of flywheel I should use. The Tranny came with the flywheel from his 97 Camaro LT1. The 350 has a 2 piece rear main seal and I believe it is an internally balanced motor, but I do not know if the motor was ever balanced after its rebuild. The previous owner provided limited information about the motor. Can I use the flywheel from the LT1 or does this mean I have to use a neutral balance flywheel? Any and all help is appreciated.

Re: Flywheel for T56 swap
U can not use the LT1 flywheel since that is a 1 piece rear main seal u need the custom flywheel that cost around 400-500 bucks
