Oil Restrictors

Hi everyone. This is my first post on this board outside of the intro forum. I did some searching and can't find a strait answer. My question is: I have a 468 inch BBC with a Comp XS290S solid flat tappet cam and Comp pro magnum roller rockers. The engine is still in assembly stages and I wanted to know if I should install oil restrictors. I have a melling HV/HP oil pump and remember hearing that a solid lifter cam and roller rockers need less oil to operate. The motor was running last year with a hydraulic cam and roller rockers showing 20-25 psi at 800 RPM idle when warmed up. I don't want to install oil restrictors unless I have to. Thanks to anyone that can help me out here.

The lifter will serve as the restrictor, so no, you don't have to install restrictors in the galleys.

To ease your mind though just call the lifter/cam manufacturer for verifcation, I'm sure they give you the same info.

I agree. The lifter will meter the oil that goes through it. Plus it doesn't make sense to supply any less oil to the valves, which are the least lubricated moving parts in the engine to start with. Another thing to think about are the valve springs. They need oil to be cooled.

Why would someone want to restrict oil from the engine? I thought that the more oil pressure you had was a good thing

Restricting oil to the top end only. You don't need that much much oil when running solid roller stuff. To much of it causes windage as it falls back down onto the crank. That was the way ten years ago or more. Now with huge oil returns and better oil baffling and current trends to windage, you don't need the restrictors anymore.
