There is never too much oil pressure unless it hits 140
springin Bob If you are running a Cleveland motor how much special machine work was done? This is also if built a certain way a high rpm motor.
Idle pressure is nothing to worry about Mine starts at 125+ with an FE motor and drops down to 35-40 at idle (850 rpms) I run between 75-80 psi at the track. I have not seen washed out bearings from high pressure oil yet. I have been running this setup in my car since 98. I did a stroker kit 3 years ago to a 482 and still run the same HVHP oil pump.
There are some trick to help your motor live for a long time. Adding oil lines to the oil gallerys from the front of the motor to the back helps the valve train. Added holes in the head gaskets helps remove extra heat if raciong the car. There are some others that I would have to look up.
Bob, I know this from 30+ years of motors, Too much pressure may wear out a distributor gear and be hard on a camshaft gear, but I have never seen too much oil pressure sieze a motor unless the cylinder is filled and hydro locked. Cleveland motors are like FE motors and need some extra help to extend there lives if you are a hard driver or like to race. Most stuff can be done at home with basic tools and time. Between 60-75 psi is good. There is a kit to limit oiling to the head, Moroso #2205, Check it out to help the motor. Lifters that are oil controlled also help keep the oil in the right place. There is a old Super Ford Mag that gives you a complete how too help the oiling problems of a Cleveland motor. I will have to look for my copy unless someone else has it here. Rick L.
