Valve covers
I've noticed that some 72, 350's (non LT-1) have a rubber oil fill cap and some have a metal tang oil fill cap. Can anyone enlighten me on which is the OEM one, or did Chevy have two styles that year?

I am pretty sure that optional engines for 1972 (and also all 1971 engines) also used the push in rubber oil cap. So, the aluminum LT-1 valve covers for these two years would not accept a twist on oil cap. Same thing with big blocks but I think the push in cap went until 1974 on big blocks.

I came across a pair of the 72's from an old friend who had them stashed in his attic for 20 years. These are the rubber oil plug type you are talking about.
