So I just got my engine back from Dan Strezo at DLS and put it in. 3.8 Stroker motor w roller cam/valvetrain. Performed two heat cycles with Brad Penn 30W w Zinc additive for engine break in. Drained and then filled with Dans recommendation of normal Valvoline 10W30. Running a WIX 51036 filter.
Hot oil psi is good, 40-60psi under throttle. My concern is 9-10psi @ HOT IDLE. It goes up right away though once I step into the throttle. GM service manual mentions nothing of hot idle oil psi specs. They just state to check it at operating temp @ 2400RPM and look for 37psi. I have that so am I good....Just seems low @ idle? Is that ok? Does the engine still need to break in? Should I run thicker oil?
Thats my only concern otherwise engine seems to run smooth.
