I am trying to decide which way to go with my 440 street build. Milodon or the ebay special blueprinted melling pump?

For normal street builds or mild street/strip setups, I just use a Melling HV oil pump. CHIP

The Melling HV is all you need. Don't forget it uses longer bolts.

I use a std. volume pump on my 440. You will find that most racers use the stock pump. The reason is the HV pumps more oil than the motor needs. HV pumps = HP loss, worn timing chains and oil blowing past the seals. I do port out and remove the as cast finish and radius the sharp turns on the internal passages on the stock pump to make it more efficent.

For a full rebuild, a standard pump should do fine. I did a backyard hone'n're-ring so I went with a hv pump. The excess pressure is by passed right back to the pan, so I don't think it's a problem at all. But then I do also run a 7 quart pan/pickup. On a worn motor or one with fully grooved bearings, I'd say the HV is a good choice, on a fresh motor with regular bearings IMO the HV pump is unnecessary.

A std vol pump. There have been a few reported failures of Melling HV pumps. Melling and Milodon are both good brands. What brand are the blueprinted ones on eGay? whichever one you go with clean it/check the 3 or 4 clearances that there is a spec for & ESPECIALLY make sure it turns freely & no binding & I would port it to up the flow & reduce the stress on the shaft/gears.
