If you increase rpm, does the amount of oil increase?

sounds like you still have some air in the lifters.
are you trying to adjust the lifters?
if so don't worry, its just seating everything in.
as for adjusting the valves running, if your using stock rockers, then 1 by 1 back off the adjuster nut till the rocker starts to make a "clack" "clack" type of noise. then turn the the nut inward till the noise stops, then give each one 1/2 to 3/4 of a turn extra. wait for it to smooth out (it will run bumpy till the lifter bleeds back down), then move to the next one.
ps, there are these little clips you can get cheap for doing this job called "oil deflector clips", they keep the oil from squirting all over, or you can use a towel folded over flat over all but the one your adjusting.

yea i have the clips... ive adjusted the lifters on another motor before without the clips. what a messy SOB.... the motor has like 30 miles on it. and a few hours of running in the driveway.... ( i exagerated a bit with the round the block three times)... So does this still hold true that the lifters still have air in them? \
Oh yea... as for adjusting i was just doing a quarter of a turn.... But i would rather make the adjustments with the motor off. Its kind of a bitch to hear exactally when the lifter stops clacking.....
and one more thing.... The valvetrain seems to be louder then normal... Whats up with that? thx a lot....

what kind of oil pressure do you have? the oil pressure isn't a big issue , but it helps if its above 40-50 psi, stock pumps put out 30-35 psi. the biggest thing you need to remember is not to rush things. the lifters & push rods work on volume not pressure, so if the thing is bleeding off pressure somewhere you have to deal with that. the chevy systems aren't that hard to deal with, you just have to have a little knowlage to avoid mistakes.
you have to kill the ignition and pull the plugs. its easyer if you use a connector for a compression gauge to reach past headers & stuff. you have to bring each cylinder to top cent of compression to set the valves by hand. secondly you have primed the lifters so its a little more work.
back off the rocker till you can turn the pushrod by hand, then slowly turn the rocker to tighten it as you twist the pushrod. when it stops turning then turn the rocker an additional 1 1/4 turns. then move to the next rocker.
heres the kicker, since you primed the lifters you will have to wait a little for each lifter to bleed back down, it can take a while , But as you move through the valve train you will notice them loosing up. after you do every valve go through and double check the rockers to make sure the lifters have bleed down.
and "beware" if you have a high lift cam and the lifter doesn't bleed down then you have the potential to bend a valve. please be careful. good luck

Without the clips on I have had them squirt over the fenders with a high pressure/volume pump

i know the builder put a melling high volume oil pump in it... my Pressure seems to be around 70-75....

75 psi isn't going to hurt anything. I have run them the Melling pumps in my old bigblocks and they do great.
