I have been reading posts like this all over other drag racing forums which makes me slightly less worried

I would cut the filter in half like right now.

20/50 is way to thick in todays world.
I run 5/30 RP XPR, 80 Cold, 30 Hot Idle, 70PSI at 7200 RPM.

I built the engine. The clearances were 0.002 with plasti-gage...I don't live in Georgia, 50 is not thick if you want safe operation, at least thats my opinion. I'd rather have thicker oil to save my parts even if it is less than optimal

small leak in rad, stock flex fan, like I said I just had to get the car running to break it in and seat the rings. Kinks need to be addressed still


Thanks fellas, will drain the oil, check the pump and filter and report back!
