Thank you all for comments. I had not thought of the U joint.

I jacked up one rear wheel, put the transmission in reverse and the overdrive in low. I can move the wheel back and forth about 1.5 inch at the tread. I hear noises in the differential but not near the transmission (U joint). I think the movement of the wheel is due to the differential gears and perhaps a little bit of slack in the ring and pinon, but it does not seem like there is any issue with the U joint. No noise and it does not feel like there is any movement there.

The car has a high compression head (5.5:1) and stock manifolds and carburetor. It has a high lift and high duration cam and larger valves. All the weight of the flywheel was taken off at the outside diameters so the momentum is reduced more that what would be thought by just comparing the weight with a stock flywheel.

Keep the comments coming.
