351m/400m Flywheel
I am swapping a 400m out of an automatic 79 into a 79 that had a 351m 4-speed. My question is what ounce flywheel I need to install as the 400 had a flexplate on it. Any help will be greatly appreciated.

28 oz. balanced, 180 tooth flywheel. The flywheel is the same for the 351M and the 400.
