I'm also installing a 39 tranny with 28 tooth cluster gear for a better shifting ratio.

The stock Model B flywheel seems like a good compromise to improve acceleration without losing too much stored energy for hills? Or it may not make much difference?
I'd really like to hear from someone who has tried the B flywheel on the A crank, did it help performance, create more vibration, or made no difference at all?

I appreciate any help you can give!

The first question I would have is, was the Model-B flywheel balanced to the rest of your engine? If so, how do you plan to rebalance a new flywheel assy. to your present rotating assembly?

FWIW, you will likely find the present flywheel assembly will be fine with the cam that your engine has unless it is a brand new cam. It has been my experiences that if yours is a reground camshaft, they do not produce the same low-end torque as what the IB330 camshaft does. If so, the heavier flywheel is not going to be of much advantage anyway.
