Re: Optimum Quench? Help, ordering gaskets... (VETDRMS)

Re: lifter valley vents (clem zahrobsky)

Thanks for the input Clem, especially, concerning the trap door tip. Obviously, sucking the daylights out of the crankcase till pan distorts, is not the answer. :)

Re: REV Kit Experiences? (No Go)

If you have an honest, accurately measured 360# at max lift, barring extremely heavy valvetrain components, I don't see much of a problem attaining your target.

Depending on the lifters you are...

Re: lifter valley vents (clem zahrobsky)

Clem, rather than a passive system, I prefer a more aggressive crankcase pressure evacuation vacuum pump setup.

Re: lifter valley vents (speedjohnson)

By chance, are/were you using a HV oil pump at the time? Regardless, seems odd that the oil would not drain down (adequately) either from the front or rear. Sounds as though, forces prevented the oil...

Re: REV Kit Experiences? (arnold)

If you are using the rev kit for more spring pressure, you are not using it for what it was intended, as SJ noted. Not all spring materials are mfrd. equal. More impotantly, install springs at the...

Re: lifter valley vents (gkull)

You're stating the valley pan seals well enuf to prevent oil from draining into the center holes, and thus over the crank?

Re: Recieved my AFR's today !!! (SmokedTires)

Obviously, the 'race ready' heads are hand ported. I trust they were ported at AFR? Did they by chance, give you any specs as to port volume AFTER the porting?

Re: Crankcase Ventilation ideas. (CentralCoaster)

Why not leave the oem system in place, and supplement it with a system that operates where the oem leaves off, under WOT or other conditions of low engine vacuum.

How 'bout an electric driven...

Re: if the oil pickup is too close to the pan? (Matt Gruber)

My impression was, that you are having problems. If you are, I don't see how the pickup depth can be contributing to that problem.

Re: Changing rocker ratio -- What's the impact on duration? (gcrouse)

Agreed! My error for not taking into account, that it was implied, the original, and followup posts were referring to duration figures taken from .050" lift, when I responded.

Re: Gapless Rings and PCV system (GRX)

You need not worry that the oem PCV system will generate too much vacuum in the crankcase. Besides, how much vacuum is generated by the oem PCV system during WOT?

Re: More On Ring Gappng Theory (WashingtonRacer)

I disagree. It's building pressure cuz the leakage past the top ring is being stopped by the second ring. Has little to do with A/F ratio.
