Again, my question was really only about the oil weight. I wanted to bring the pressure down, so I was thinking of 10-30 instead of 10-40.
I dont want to go to zinc land again.

WITH a can (just one) of ZDDP it will be just fine. Without it its a crap-shoot.

What is ZDDP? Can someone let me know? Thanks
Basically it's zinc. You can search the old posts here and read a long long thread on it.
Government is taking zinc out of most oils. Old cars with flat tappets among other things and theory suggests it is needed. Kind of like the lead in gas before hardened seats etc.

The other day there was a post that a guy didn't want to run light oil in his early rebuilt engine and wanted to run 15/50 or 20/50. Not a racing build either. Never did get a good reasoning to this. The OEM recommendations of the day was a good 10/30 oil and in was not uncommon to see 100,000 mile engines. If you are running stock valve springs with relatively light rates I don't think that the zinc content is that big a deal either. It is with higher spring rates and fast rate cams that these thing multiply to disaster.
Clean it, if it's Dirty. Oil it, if it Squeaks.
But: Don't fix it, if it Works!

Well I have to agree. I don't think the zinc will hurt at all. My engine was built for racing but it will not see it other than some street back road fun. I just wanted to bring the pressure down some so a lighter oil (like stock 10-30) seems like a good choice. This could go on forever about synthetics and zinc and what momma used to do, but my old E body has 118000 Original, never rebuilt miles on her and she still runs real strong. I had to run 40 weight in her to get the pressure up as she's a little long in the tooth like me.

Well, all I’m going to say is a look back into my latest posts will show my humble opinion on this topic. I’ll just add, what if 118k is just a drop in the pan when using new technology oils compared to the dino oils of old...
