440 4 speed

Most all of the cast cranks were not drilled deep enough. I can tell you horror stories about Wheeler Engines back in the 70's and 80's that thought it would be great to only carry one part number for auto or stick instead of two. Problem is the cranks were to porous or they drilled into an oil galley. The shop i worked at back then did all the Sheriffs cars for Hillsborough county. I can't tell you how many of these POS I installed that leaked! I would not drill it. Use the different style bearing and shorten the imput shaft or install a steel crank kit in your 440.
