340 oil pressure? Help

Yeah I saw it was a roller WELL AFTER the initial post that SHOULD HAVE included that info. I didn't jump all over anybody. Are you head of the snowflake club now?

Right, except if you’re some expert that actually deserves a tech editor badge you should probably have asked the guy if he had a roller cam in it before you called him stupid in your very first comment.

But you didn’t. You started cap smashing and calling him stupid before you had enough technical information about his build to even have a clue. But you couldn’t possibly ask those questions, because he should know to post that for you.

And then you went right back at him, telling him he should read up on something first when you can’t even read all the information he has posted in this thread.

And now you’re calling me a snowflake because you’re having a tantrum about being wrong? Sure buddy, ok.

Yeah I just checked and the plug is in I'll try changing the oil when I get the chance and go from there. It wouldn't surprise me if the shop built it a little sloppy unfortunately I heard the bad reviews on him after the fact and the good ones before lol thanks for the advice I'll keep you posted on the outcome

Well, try the heavier weight oil and see what happens. Get some more run time on it and see what the pressures do when the engine is fully up to temperature. Those aren’t the pressures I’d want to see on initial cold start up, but that doesn’t necessarily mean you’ve got problems yet.
