Did the pickup fall off? Do you have the bypass blocked?

did you check any clearances on the pump or just visually inspect it.

Also 10w30 oil. Is this synthetic? It seems really light to use in a race car. I would think a heavier oil would be better as hot as our motors run.

I agree if this is not synthetic it should be 20w-50. What brand of oil filter? Hopefully it is not a Fram.
PS- A new oil pump is even a must for a low budget racer, and I personally use the high volume pump. Before I use it I take it apart and use 240 grit emery paper on a dowel pin to make sure the the metal is smooth where the bypass is cut in. Without the preparation the bypass can stick. Make very sure to clean out all debris before reassembly.

hey it sounds like your oil filter may be stopped up, i always change oil filter after break-in of new engine because you can never get all the lint out of engine when you are building it. if the filter is stopped up it will have decent oil pressure at idle but when you rev engine oil pressure will drop.

sounds like the pan/pickup clearance might be too close. make sure pan isn't bent up to the pickup.

dont want to sound stupid ,but are the cam bearings in right ?all oil passages have a hole, and must be lined up properly .but it does sound like line bore is problem.go back too using 20/50 please. oil brakes down to fast when in racing application. do not use fram oil filters!!!! just my 2 cents worth
