I now do Titan Oil Pumps on everything I do. That includes low budget street/strip SB engines. The old days of us all using Melling Pumps has been gone for awhile.
Now in a way becuase Melling changed gears to screw racers, it put me on the tral for better. I found better and in my opinion it is the best and is one major engine concern I have no concerns about now. Yes' It is hard to convince someone to spend $400 plus for an oil pump in an engine that is maybe $4,500 but I am doing them a favor.
Usually when I show them how thin the new Melling pump is and one with busted powdered gears is all it takes. Oh' I also have a 55 HMV here that also doesn't turn very well either. Good object lessons to justify a one time purchase for the life of the engine. Same with the oil filters we are now doing.
