My main issue with the Detroit was on pavement or hard pack. Just pulling out of the driveway and any amount of turning would send shockwaves thru the drivetrain to the point it affected shifting into gear. Again, this was never noticeable when it had the automatic transmission. It was very noticeable after the 4500 swap.

It'll sure do that, especially if it's working real good. It's worse in some vehicles than others too. I'd imagine you probably had some real good tires that were either big or gripped the ground real good. You mention even hard pack, so I'm thinking wide tires. Soft rubber or smaller tires that don't grip that ground as good you won't notice the shock through the powertrain near as bad as you mention since the tires are more forgiving. You just had some good tires so you felt every bit of it.

They can, they're for sure stronger in the Full Floater by design. And when they do fail, they don't explode like they do in the 10 and 12 bolts. They'll either strip the teeth off the governor ring or break the spring loaded governor itself. The good thing there too is, since it don't explode, it won't leave you stranded. It just won't lock up anymore is all. So many times, people will claim it's great and there's is holding up and they don't realize it's not working since they're able to drive and it's not making any strange noises.
