It bumps right up and you are good at RPM, Your large oil lines and T-Stats all contribute, I ran a build that was almost exact for 6 years and my builder said it was normal.

builder thinks that the lifters and the valve spring oilers are bleeding off some oil and lowering the pump volume at low rpm's. since they are already hv pumps do the new billet melling pumps provide any more volume?

I know I ran the melling select pumps, I opened lifter bores to .0022 and also opened lifters to increase more oil to rockers, guys said I would lose a lot of pressure, I did not, also have big clearancing.. ran 80 PSI, anything over 1500, was 3-40 idle

Spring oilers will eat about 10psi. I put check valves inline... I adjusted them to close anything below 35psi (no need to push oil up there at idle)
Anything below 40psi they are really just dribbling not really spraying anything .

and thats the question i'm trying to answer. pull them but do what?. is there anything i can do to bump up the pressure? they run great, idle like stock, and throttle response is unbelievable. is there really anything wrong? i'm taking it from the posts here that there isnt. these engines are a result of 7 years of planning and saving money to build. they are pure overkill from a build standpoint. every part on these things are capable of handling much more hp than they are being asked to now.
