oil pres question -305 v8

Close. '78-'79 for sure did. Maybe '80 too. Either way, OP's oil pressure is great.
My recommendation on exhaust is to order the pieces for a GN from Rockauto and let an exhaust shop mate it to the Olds headpipe. It fits in stock location, doesn't hang low, and sounds good without being too loud. Plus the tailpipes come out in the proper Olds neighborhood.

Correct, California bound Olds and Pontacs had Chevy 305's for those years

Yes, I know the differance between an olds & a chevy motor, but the stores like napa, carquest, autozone & orielly
don't, catalog wise. thats why when I go in I have them I have them turn the screen so I can tell them to click on the "Y"code
at any rate, it's a 5 litre & however the catalogs round it off.
I did parts for 22 years at WORLDPAC in a previous life,
It's easy to tell it's an olds by the crappy design combination intake gasket/ valley tin design-
Should have designed it with a boss & extra bolt on the drivers side

Reason for asking about oil press is car is fairly new to me & my other car Porsche 928 has 5 bar - 70+- lbs
