hey, Terror, thanks for the reply...

I get 30psi at 800 idle when everything is on the hot side, which I think is plenty of oil... I've turned it up to 1100 since this post but vacuum is still in the 4-5" range... I'm still running 6.5" power valves for now and I will be swapping to 4.5" in the near future... I keep a close eye on the plugs and haven't had any fouling problems yet... I should be at 2.5-3.5" power valve but I don't want to risk the lean out on the big end of the strip. I'm probably close to the point I ought to plug the PV's and jet it up, as Pat McCarthy suggested but I'm reluctant to do that for a still street driven car...
