Those running melling high pressure/volume oil pump please come in! Have you had any issues with your high pressure/volume melling oil pump? How many quarts of oil are you running with your stock oil pan? read of possibly running the oil pan empty. also how long have you been running your pump?
Thanks Raul

I'm running a 10296 (high volume) utilizing the stock pan and 6.5 quarts. I have never cavitated the pump due to inefficient oil supply.
I am, however, having issues with fluctuating oil pressure (Delta P = 7-10 PSIG), but I don't think it is directly related to the Melling pump.

Agreed, we have done alot of testing with them and have not had issues with oil return with the 10295 pump you have! For that matter, it has only been some VERY severe testing at high-rpm and for extended lengths of time that we'd had any issues with the high-volume 10296 pump.

At high-RPM for extended periods of time it will pump more to the top end than can return on a stock oiling system. With a few modifications though, that can me remedied to a certain extent.

Which pump are you guys using on your TSP25-427LS7LB long block packages? Your site says "ported oil pump". Is a Melling or ported GM?

That's the ported GM LS6 pump.

Both are nice pumps...just be aware of the clearance issues with the Melling pumps, particularly on double roller timing sets.

I had planned on running a 10295, but let a vendor talk me into a 10296 since they didn't have any of the 10295's in stock. I have a stock shortblock heads/cam car, and I think I'm running into this issue whenever I do any spirited driving for more than a few minutes at a time.
