Default Oil pump Melling 10295 vs 10296, 295, 296

Had to rebuild my L76 in my Pontiac G8 GT due to lifter failure. Just a basic job. Re hone and put new bearings and rings in it plus DOD delete and a pretty aggressive cam. I’m trying to save cost where I can so I’m looking for opinions on the oil pump.

I’ve found most people run the Melling 10295 or 10296 oil pump. I’ve also found the same Melling pumps in a 295 part number and 296 part number for significantly less money. The pumps look the same but the 295/296 don’t have the low pressure spring which is fine I suppose. Is there no difference between the pumps 10295 to 295 or the 10296 to 296?

295 = standard volume, standard pressure
296 = Chrysler oil pump
10295 = high pressure, standard volume
10296 = high pressure, high volume

I did a cam swap and went with the 10295. The guy I bought my kit from (also a builder) said I didn't need the high volume 10296.

Bottom line- you want more pressure, not more volume. 10295 is your pump.

On the DOD delete, I’ve heard you could tap and plug the holes coming down for the collapsible lifters in the block. I have a dod delete valley cover with the o rings and all. Was just wondering if it was a good idea to go ahead and plug the holes before I put the block together?

Yeah, good insurance in case of O-ring failure. It CAN happen...

Good idea sure, but you need to do this step with a bare block. Lots of shavings go down the holes, so you’ll have to wash the bare block thoroughly to do this correctly.

Sure thing. The block is still at the machine shop. I may ask them to tap the holes for me so it’s good and clean.
