Sourcing Allison MT643/653 Flywheel for Chevy 366/427 in Ohio

[K-Unit]

Hello all. I am looking for the flywheel that mounts the allison mt643/653 transmissions to the 366/427 chevy big blocks. I am located in Ohio. I have included a picture of what the flywheel looks like as well as a diagram from the service manual I have. If you have one to sell please reach out.

Have you called Dartco Transmission? I used them a couple of years ago when I rebuilt my MTB-643. They had everything and were reasonable, price wise.

Decades ago there was a place called S and J Chevrolet that was the place to go for that stuff but they are gone. What part of the country are you at?

You may want to try the truck wrecking yards in California's central valley. It was an agricultural hub and a lot of gasoline allison trucks were used there. Now that the glueheads have declared war on older vehicles a lot of them have gone to scrap. Look in Bakersfield, Fresno and Turlock.
