Reply to "Oil Pressure??.. What say you??..."

The rule of thumb is you need 10 psi for every 1000 rpm. 7000 rpm, 70 psi.

I wouldn't feel comfortable with only 40 at 7000 with any engine.

Now if you are going to run a Cleveland to 7000 or above it is highly advisable to sleeve the lifters and that will fix the oiling issues for all intents and purposes.

When people talk about Clevelands having high speed oiling problems they are talking about over 7000 rpm. Even the old Pro-stock Clevelands that Gapp & Rousch ran were just stock block Clevelands with oil restrictors in the lifters. Those were 8,500 rpm engines.

With all the talk about the oil pump relying on the roll pin in the distributor shaft how many do you actually know of that have failed? If it does you will loose the ignition gear drive and the engine will shut off anyway.

Run a TRW HV oil pump. It will give you 80 psi cold and never drop under 65. If you are running a hydraulic lifter camshaft you could use that pressure anyway to try to approach the advertised lift on the cam.
