Both Melling 10832 have 10833 oil pumps have screw in plugs for the bypass spring which can be adjusted in to bump oil pressure up a little.

 

the mellings pump should be set around 50 psi which really is plenty

 

whats the difference between the standard melling pumps and the 'blueprinted' pumps?

 

I have a 10833 in my 393. Cold pressures are normally 40 to 50, but warm pressures are often below 30. should I still be seeing 50?

 

depends what your needs are... if you need serious pressure Call titan. we idled over 100lbs with the race motor. and would see around 120 down track
