Crank Hole Finish Size For Pilot Bushing

Is the crank drilled deep enough to accommodate the input shaft length?
I've seen a lot of 4 speeds with broken off bolt hole flanges.
Has the trans input shaft been shortened by someone already?
If yes, I'd surely go with the mad's snout bushing rather than the roller bearing replacement.

The crank is drilled plenty deep enough for the bushing! All of my other cranks that have the bushing in them already have almost an inch more depth than the bushing! This crank is drilled as deep as the other cranks!

The snout of the input shaft has not been modified, and with the bushing in the correct place will work as stock!! Geof
