Is this a stock engine?
What kind of oil? (Synthetic or Dino)
What weight?

For reference, we raced with a pre-1991 2.3 (4 plug, carbureted engine), built to IT rules but with whatever clearances were stipulated in the factory manuals with Sythetic 10w30 oil and would race at about 45lbs of oil pressure (hot) at 6000 rpm. If I remember correctly, it idled at about 20-25 lbs.

We did that sort of thing for years with a couple different engines and never had a problem.
