Get it to stay Flat at 12.0:1 to keep the valves cool and stay out of Detonation.

Ted.

Yeah I was hoping to limit it to 12.3:1 at high RPM, per Jordan Priestley's advice. I have to get another dynopull on a Dynojet, per NASA rules. So I can have the tuner richen it up.

A relatively cheap step in the right direction is an Accusump. I don't have one but there are builds online that install it right under where the passenger window wiper is, over the cabin air intake. It's a piston that holds an oil reserve and pushes it out if pressure drops. Pretty cool. You could install that in a few hours I bet for a few hundred bucks.

Looking good. Dam similar to mine. Only I get to take mine back out to figure out why I only have 12-14 psi oil pressure while idling. I'm thinking its loose bearing tolerances.

Check the cam retainer plate they leak and will cause low oil pressure.

Or check the cam, last time mine hit that kind of oil pressure my cam was gone.

OP... did you ever get some numbers on a Dynojet? I recently went with the 416 stroker and am curious how your's does.
