I installed a DUI HEI awhile back it works great, however, it would appear that I have a substantial range with my timing, from 5 to 13 degrees BTDC. Will the proper or improper timing (increasing or decreasing) have an impact on my oil pressure? Since installing the HEI the best Oil pressure with engine hot 215degrees is 27 psi @ 2000 RPM, but it really takes a dive at idle 6 psi @ 850 rpm. with engine cooler @190 degrees 57psi @ 1800 rpm and idling @ 30psi So one thing I’m trying to do is get the engine to run cooler, maybe a new Rad or vent the hood etc
