Melling oil pump question???

What kind of oil pressure are you guys getting with a M55HV oil pump?
I know bearing clearance etc will affect this but I would like something to go by.

Just wondering but would a melling M-55HV put out more
pressure than a stock pump with a high pressure spring?

If not can I use a high pressure spring kit in it or would I be better off with a Melling M99HVS

Just got a milodon 7 quart pan and thought while Im at it I will go ahead and change out the stock pump with the trick spring kit.

You would be better served to use the Melling M-55A, which is the Corvette or Z-28 hi pressure pump. It will pump all the volume any properly clearanced SBC needs without a HP loss. I've used them for years without oil pressure problems or undue wear on the distributor gear or block face to cam gear wear. Pressure is 60-65 lbs hot at 1500 rpms. Your pressure at idle will depend on your crank clearances. I only recommend this pump for summer driving. If the application is for cold weather, use a stock pump.
