This is the problem I'm going through right now. I have some Smith Brothers custom chromoly 5/16 oil restricting pushrods (6.150 in length/ .083 wall) where the oiling hole is half the size (.040) of standard which will hopefully bring my pressure back up. It's okay now, but is too close to that 10psi/1000rpm rule of thumb for my comfort. Hopefully I'll be getting these things in the engine w/in the next couple of weeks and finally get to the dyno for a tune.
As far as hp... I've read where people are making anywhere from 450 to 470rwhp with over 400ft lbs of torque and running in the range of the 11's between the low to high 120's...

The power number you quote, are with what size heads/cams?

Thanks for the great info.
