You may not have a distributor problem. It's been a while since I worked on a 265 but there was an issue
with the early engines. As I recall there was a slot ground in the rear journal of the camshaft on 265's and
some early 283's that was not applicable to later engines. If you replaced the cam, it would not have
this slot and subsequently no oil pressure.

To the best of my knowledge, the only V-8 distributor that used a different length shaft was for a 348.
