Hello guys, I just recently bought a new 250 motor and I'm having a hard time getting my distributor to seat on the block. I didn't have this problem with my old 250. I believe the older one was a 70, and this one I believe it's a 72 or 74. I don't think this should matter.
The new motor came with a new oil pump which I used of course. Is this my issue? What's different about it? And how can I fix it?
