I guess I don't understand what you're trying to do? There's no way I'm doing anything but the 10296 on a built motor with a high RPM target. I have a perfectly good ported pump that I am not considering for the build because of the parameters I'm looking at...
What are you talking about? The M295 WILL NOT supply the oil flow of an AFM/DOD pump from GM. That's why Melling has the 10296 and 10355. Count the lobes and measure the thicknesses of the gears. .

I talked to people that build high $$$ engines daily and they've said its just as good.

The 355 seems like overkill to me. It's also gigantic.
KCS - I know you build these things a lot more than me. Any advice on blueprinting the 10296 or just going with it out of the box with me going through and knocking some casting flash out?

I assume you're talking a used pump? I'd never reuse one....if it's brand new and ported,I'd run it.
Pressure isn't the beat all end all. It's volume.

Yea,LME are idiots!lol They don't build quality stuff,you put better things together in your garage right?
Oil pressure is a highly debated subject. Personally,i think any pump with the correct shimming and porting to increase VOLUME,all pumps are going to perform very similar.
We're talking any GEOROTOR oil pump....these aren't SBC's.
You want better? Go dry sump.
If you go through and clean it out really well, lube it up, and torque all the bolts and the plug to spec, you shouldn't have any problems.

Porting doesn't increase volume; at least not significantly. This isn't cylinder heads, this is a pump. There isn't any amount of porting you can do to get an LS6 or M295 to flow the volume of the 10296 and 10355 which have larger gears. It's like a 6-71 blower vs a 14-71 blower.

No, Bryan and Pecos know better. You must be mistaken.

I know porting will not pick up flow a ton,it would be a measurable difference tho....
It's all a MOOT point because no1 has EVER actually tested the flow of ANy pumps besides the manufacturer. I understand how georotors work very well BUT we don't know other limitations in the system(from the pickup to the size of the oil passages)
Like I said,150k mile lq9 that's only run synthetic since day 1 and was never opened got the exact same hot idle oil pressure as a ported/blueprinted 10296...only difference I saw was at WOT but that could be that one engine was revved 1500rpm more.
I like spending my $$ wisely. If Pecos would've told me "go with the 10296",I would,no questions asked. But that's not what was said at all...
It's your $$$,spend it however you feel comfortable. On my $15k+ engine,I felt more comfortable using the 10296. I highly considered going dry sump but packaging prevent me from doing it.
On my sub $5k engine build that I'm only shooting for 750-800hp,I choose a ported/blueprinted m295 and took the extra $100 put it towards a $240 Harland Sharp trunion upgrade....
An AFM/DOD pump has a higher flow rate than the M295 or the LS6 pumps. The M295 is basically a factory replacement LS6 pump by Melling, but you're mistake to think its equivalent to a DOD pump.

Kind of like Katech selling the C5r chain for $150+ but u can buy the same chain at a BMW dealer/site for $25.
I said "according to an engine builder". And a credible builder at that....
I see you didn't point out anything else like no specs out there besides what the manufacturer tells us
Do some research on Vern Schumann and his oil pumps. I met him at PRI. Vern does extensive flow testing and shared flow rates on all of his custom pumps with me.

A little bit off topic here, but when is the 10296 version warranted over the 10295?
At high RPM would you run the risk of sucking the pan dry with such a high volume unit unless you get a bigger capacity sump?

If you have a pump that delivers more volume than a given engine will pass through the system, then the pressure rises until the oil pump's by pass system relieves the pressure. If the volume exceeds the bypass systems flow, then the pressure will continue to rise.
Take oil weight into consideration in this as well.
