Cutting A833 Input Shaft Question

Just when I deleted all my SB Mopar pictures on this topic !!! I was measureing my 360 motors which both had auto's behind them against my factory 4 speed crank and came to that 1/4 need. Before cutting one for the 833 overdrive I want to put behind - I'll put the bellhousing on the block and put the trans in less pressure plate etc. Then take a look....lucky that motors are out at this time.
