if youve got an extra $500 dollars to waste IM sure melling will be glad to help lower your bank balance, soorry! I don,t see where these a $400 plus advantage over a correctly clearanced old style pump
while helical cut gears will run smoother ,
( ESPECIALLY WITH THE STOCK 7 tooth SBC oil pump)
as you potentially have 2 or three gear teeth in various stages of gear tooth contact
(depends on the angle of tooth engagement)
and yes the design will reduce a tendency to produce a pressure pulse, I have not seen this as a major issue.
simply swapping to the standard volume and pressure BIG BLOCK 12 tooth oil pump in a SBC engine all but eliminates the pulse and pressure and volume issues a sbc oil pump has.
adding "ST" to the end of the existing melling SBC OIL PUMP part number denotes the helical gear set option
QUOTE"
If you're serious about building the ultimate wet sump system, these 1-piece billet aluminum oil pumps with integral screened pickup are the only way to go. They provide smoother oil flow with less internal drag for 5 to 6 more horsepower and eliminate the possibility of the oil pump pickup falling off. Pumps fit Moroso, Milodon, and Stef's wet sump pan; no need to buy a new pan or modify the old one."
