Best oil pump for fresh rebuild or tight tolerance motor

very good oil pump

installed in a 2010 camaro ss to replace the OEM oil pump that had a failed oil pump relief valve.no issues, same oil pressure.go with this instead of high pressure and/or high volume if you're running stock bearing clearances etc.

Great oil pump

If you have active fuel management/cylinder deactivation on a Gen 4 LS (2005 and up), you'll need the Melling M365 or M10355HV as those supply the correct oil pressure and volume

Now i have steady oil pressure

Great oil pressure with this unit.

I've put a few thousand miles on it and continue to have great oil pressure (60 psi).

Great oil pump for a stock motor I put in a set of 4 main bearings and a full set of 8 rod bearings

Genuine Melling oil pump Had 40 psi with cold start and idle

Worked great for my 1997 corvette, used the black o ring and have great oil pressure

Has way better oil pressure now

after engine was warm it carried decent oil pressure but the new OIL PUMP boosted pressure about 20 pounds to 55 psi

Great ls oil pump
