Oil Question
there is nothing to worry about there. The first power pull of my 340 it was at 102 PSI on the Penn 30wt BR oil. I changed it to 10-30 Penn partial syn, and now about 70 PSI cold and 50 psi hot at idle. I would just stick with the partial 20-50. For the Cosworth racing engines my brother builds, (60’s/ 70’s tech engines) he runs .0008 mains and .001 rod/ cams bearings, we run 20-50 Penn in all of them.
These pics are right before the teardown. This motor was about 10 minutes from blowing up as we found some dumb **** from the last builder. When one of these blow up, it’s a 100 grand of ****…
