Need some help - loosing oil pressure at high rpm's

[madmaxx]

Hey guys, reviewed my findings with some local engine builders who helped me in the past to reciprocate info and I called Precision to thank them. The consensus of the group was not to touch anything. They loved the 67 psig at 6K rpm. Precision said the 351W oil pump shaft is much heavier than the 302 and it is not a problem even when cold.

By the way my hot idle increased at 800 rpm from 27 psig to 41 psig!!!!! at 1100 rpm it is 55 psig.

I called Mellon and told them the story. Told them to send me a prepaid shipping lable and I will return the pump and springs so they can find the error in their ways. Told them I dont want money, credit or anything. Just learn from their findings so as to avoid somebody else having an issue. I told them it would be good in a 1975 Ford LTD but not a high performance street engine, LOL.

I hope Randall doesnt see my post on oil pressure above or he will loose it. More is not always better, I do learn but not very fast.
