Just wondering if anyone knows what their engine bearings clearance specs are and what kind of oil pressure they see at idle cold and hot and full throttle. I have a new boost engine that is showing different pressures than my stock bottom end setup.

I'm part of the way to building a stroker engine. I know my clearances are right at .0025" for the rods and mains, but I don't know my oil pressure yet as I've not assembled the engine yet.
What are your new bearing clearances and oil pressures?

are you using the stock gauge or a secondary gauge?
i have the loosest ls1 ever built and with the stock oil pump i had more that that.
if you are going by the stock gauge try using a regular gauge tapped into the system.
if you are running a big cooler or are feeding your blower/turbo use a HV/HP oil pump.

Having 25 to 30 hot at idle, is good I don't think you have anything to worry about.
