Just totally re built my 454, new crank,mains & rod bearings, new rings, cam & lifters, when hot on idle its 20psi, above 2000rpm 45psi, does this seem Okay??

Sounds perfectly healthy to me. What kinda oil are you using?

20/50's, I am tempted to put a HV oil pump on, but I assume to much oil press, might cause oil leaks?

20 at hot idle and 45 and up at 2000rpm is perfect. General rule of thumb is 10 pounds of oil pressure for every 1,000rpm.

No a HV pump will not cause leaks just is like putting on a bandaid with no cut. You don't need it. I have one in my BBC but I am one of those guys that goes over something a 100 times till I talk myself into it. Anybody else have 7/16 rods in there 6500 rpm oval port motor? See what I mean.

Mines 45 at idle 75 at speed too much? I have the much debated Melling HV pump

Has it produced any leaks? running at that pressure?? I have ordered a Melling HV pump, but really undecided weather to fit :confused:

You do not need a HV pump for a BB, the stock one is more than adequate.
