My MSD distributor will only go in this far, it’s same size as the original one and I have turned over the engine to try to seat it. It feels like it is hitting the bottom of block.

It likely is sitting on the oil pump shaft, 5.0 or 351?

ARP Oil Pump Driveshaft? I have the same issue right now. Directions have been to cut the bottom of the distributor or change the oil pump driveshaft.

Apparently my ex-husband made that mistake.

Usually jiggling it and/or lightly tapping it while pressing down usually gets it to seat.

If that doesn't work, I've used folded sandpaper, or a small file, and lightly clearance the inside of the hex on the distributor to get it to slide on easier. You can use a 1/4" socket drive or the like to test the fit.
