Will A Model A flywheel work on a B motor?

J Franklin · 02-29-2024, 02:21 PM

yes

Yes, UNLESS (if I remember correctly) you are running a Model B transmission in which case it will interfere with the bell housing unless you have it cut down slightly.

Nope, not a B transmission Thanks for the assist!

A flywheels are heavier than B's.

I have a lightened A flywheel but now that I am swapping in the B motor I wanted to be sure I could use the one I already have. Looks like I can!

I think you'll need to trim the back of the B oil pan to use the A bell housing and trans.

That’s what I understand although I have not seen how it all goes together yet.
