No lifters clattering, just put new oil.
Had gauges installed for a while but it always showed 12 to 14 psi even when driving. Now showes 50 psi +/-while driving thats why it made me curious. I also had issue with mechanical fuel pump because it was pumping fuel into the block. Fuel pump is replaced and thats why I replaced the oil recently as well.

I think I just going to watch oil pressure for a while to see what's doing.

Pulling the oil pan would help to replace the rear seal because it started to leak alittle bit, unless there is other way to replace it without pulling the oil pan completely and draining the oil.

Thx

rogal_tx , I have a 76 olds 350 that has been "refreshed" with added bolt on parts " not rebuilt ", my oil pressure at start up (cold engine) runs around 38-40, now up to temp at a stop light it will drop to nearly 0. Back on it at WOT it will go back to 38-40, off the gas it will drop, on the gas it rises. ( running 10w30 ) As others mentioned I don't think you have anything to worry about until you hear ticking.
Hope this helps
Cheers
Eric
