Anyone know what the tooth count is or the OD of the Mustang II C4 flexplate? Someone told me B&M makes one of these with the 50oz weight on it already, I looked on there websight bt it doesn't list it. OK..now for everyones opinion, LOL. I'm going pull this motor and drop in another roller 302, my plan is to use the block from the exsisting motor and build a 331 or a 347 over next winter. should I consider maybe doing a T-5 swap while i am putting the other motor in? I don't plan on doing a whole lot of highway driving but the 3.80's in the rear seem steep with the 3 speed auto. Thanks guys...Pic's this afternoon

I got my flywheel from Art Carr I think......don't know exactly how many teeth are on it though. Just tell them what you got and they can help you out. I was pretty much in the same boat, 50 oz. balancer and had to order 50 oz. flywheel

Not only a machine shop but a shop that can dynamically ballance.

And Brian, I would make damned sure it has the correct harmonic ballancer on it.

I wouldnt build a stroker motor from a newer(1981+) block. Those blocks are a LOT lighter than the older blocks, and the main bearing support webbing is drastically thinner. Not a good thing when you're swinging extra stroke and making a lot of power.
