I discovered that the early 273 4 speed crank that was in my 340 block wouldn't allow my 727 tranny to mate up to it.
This happened of course after everything was all together.
The converter hub will hit the end of the crank at approx. 1/2 inch to bolt up.
I had to pull the engine apart and get the crank machined to allow the hub to clear.
All the local Mopar people i talked to didn't know about this potential problem.
I thought the crank was the original,that came with my '68-340 when i bought the block and crank as a used package
Finally i discovered this mystery when i talked to a long time Moparian.
A word of advice would be to dry fit your converter to the crankshaft prior to installation.
