Hemi Oil System Question - 03/16/15 04:58 PM
Ok, just got the new cam in my 472 Hemi. I'm using a custom grind solid as some folks here indicated my off the shelf hydraulic could be leaving some power on the table. Anyway, I know one of the advantages of solid lifters is higher RPM effectiveness. But a question I have is this: at what RPM do folks recommend deviating from stock internal oil system? I had heard that higher RPMs that the Hemi's oil system tended to give up. I never paid attention because I assumed it was greater that 6500 rpm. Since I was originally using a hydraulic I didn't care. But now that I may be living in the higher RPM range, I am concerned.
At what RPM is stock oil system deemed inadequate? What are options? Is the deficeincy in the pickup? Or downstream of the pump? I happen to have a used single pickup Moroso cover setup that came with my box of parts. But I am not sure it would clear the engine mounts. How do these special covers work? I assume I plug the internal pickup port and run a pickup from the pan to the cover assembly. I was looking at Moroso's web site and couldn't find any directions for their set up.
