I have a 225/904 from a 73 Plymouth Duster that I'm cleaning up to put into a 1938 Plymouth street rod. When I took off the passenger side motor mount the lower bolt hole seemed to have oil in it, and the block looked like there was a place for an o-ring to sit. I'm not going to use the original motor mounts except for ideas, just want to make sure there is no oil leak there. Any ideas if this is all ok?
Looking for #'s and tags, found the tag on the distributor that says 3755042. I'm assuming this is a points distributor, and no I haven't taken off the distributor cap yet. Am I right here?

The motor mount holes are blind, they do not go into the crankcase. The oil came from outside.

'73 should have an electronic ignition system, but if there is only one wire it has to be points. 2 wires will be electronic.

3755042 and 043 are 1973-1974 EI distributors...

The oil came down from the leaking valve cover/plug tubes.

Thanks all Greatly appreciate all input. Hope to maybe put engine in 38 for a "fitting" again tomorrow. Glad I have the 6" recess in the firewall, wouldn't fit without it.
