... My old gas 5.9 2500 HAD NO PILOT DRILLING with an automatic. You would have to either have the crank machined for a pilot, or hand drill a clearance hole for the pilot shaft, then use the large diameter pilot bearing/ fits in the pilot hole.

Why are some drilled and some not? Is it only Magnums that were installed at the factory with a manual transmission that are drilled? How about Mopar crate engines?
