hey every1 i drive a hobby stock on dirt and asphalt. we run a 383 stroker and we just rebuilt it. our first weekend out we had really good oil pressure; about 80 to 85 lbs. at full throttle. thats better then we've ever had. but in the turns i'm loosing pressure. down under 20 lbs. we put valley plugs and screens in tha lifter valley. could that be the problem? the 7 qaurt oil pan has trip doors and we have a good pump. we changed filter and checked out filter screen. any comments!

your pickup tube on your pump could have fallen off happened to me last year 70lbs in the straights as soon as i would go into the turns would drop to 10

If its a HV the p/u should be bolted to the pump.

Does the pressure come back up when you're back on the straight? If it doesn't I'd say you're trapping oil up top. If it does, i'd try a pan with more volume or an accusump accumulator.

another thing...since its not a roller cam you shouldn't plug the valley as a solid cam needs that oil to survive. Also those holes act as vents to allow blowby to escape the crankcase. This blowby could be "pushing" the oil up and limiting its drain back.
