I am doing a cam install / DOD delete soon and was super confused about the myriad of choices for Melling oil pumps. So I contacted Melling to get more info and here is what they said.
10295- flows the same volume as LS3/non-DOD/AFM stock but at higher pressure. Comes with red 70 max psi spring installed which is good for 7k redline. Also comes with blue spring for 60 psi (max 6k rpm) and grey spring for 75 psi max (7,500 rpm max). Recommended for DOD delete.
10296 (edited by Pursuit)- flows more volume then the 10295. Can swap springs for max psi as well. Recommended if aftermarket oil cooler or turbos installed or running lose bearing clearances.
10355- flows more volume then 10296 and would be considered the performance replacement stock pump for our DOD. Recommended if keeping DOD.
10355HV- flows even more volume. Recommended if keeping DOD delete and installing turbos. external oil cooler, etc.
Here is a helpful video on the different spring pressures.

There is also the stock replacement oil pumps, M295, M296, etc. which I did not ask about. In my case I ended up buying a 10295 for my DOD delete and will run it with the installed red spring for a max of 70 psi. I am also plugging the bypass in the oil pan. If I didn't I would probably end up with oil pressure issues as I have heard it bleeds off at 55 psi to protect the DOD.

Re: Melling Oil Pumps
There’s two spots were you mentioned the 10295. Was that an accident?
Re: Melling Oil Pumps
Yes. The second one is supposed to be 10296. Hopefully a mod can edit my post to fix that. Good catch!
