The original 351m/400 used a similar flexplate with 10.5" torque converter Bolt Pattern and 28 oz-in crankshaft imbalance. So I found this 351m/400 TCI flexplate with 164 teet, 11 7/16" torque converter bolt pattern, and 28 oz-in crankshaft imbalance :

It seams to match the aod, or is there another reason why it wouldnt?

I think this is the flexplate im looking at running behind my 393C i was going to just drill new wholes in it for my converter if it doesnt fit and have it rebalanced.

If just drilling holes and rebalancing it is possible, I think its a way to go... Im gonna ask around and trying to get opinions on this

I know one way to get around the whole darn problem is to internally balance the engine and just use a neutral balance flywheel and dampener. As long as all wholes are made equally it wouldnt be a problem.
