What oil weight?

20w50? try a thinner oil

0w20? You got some tight clearances.

10psi per 1000 rpm is a rule of thumb, for the SBC. the LA can run less happily. 50-60 psi is adequate unless you are running some crazy rpm.


They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
