went racing last night and had motor problems all night. only like 25-30 lbs of oil pressure and motor flattens out at about 6000 rpms. any ideas what may be causing this? is it something in the motor or maybe msd caused?

MSD won't kill your oil pressure. I'd be looking in the pan for that problem.

Limited RPM can be valve springs.

How many nights/laps on the motor?

first night on the motor, all brand new.

Any sleeves in the block? Any restrictors and where are they front or rear , oil pump used? Just a few places to look. Glassman
