Oil pump choice for LS3? Need some advice on LS3 oil pump.. bought a new short block and they are telling me to run a 10355 pump in it... mind you this is in a F Body with 5 qt pan .... isn’t that a bit much pump? I was thinking about staying with a 10295 pump.. heard the 355 could literally suck the pan dry at high rpm

Not doubting you Patron, but Tony has changed his ways these days. During my build, he told me a couple of times that a high pressure pump wastes hp. He sold me a std pressure pump, that he ported for more volume.

If I had to it all over again I'd buy the pump like Tim *87Hatchback along with SAMTech used on there EMC Lsx: Great for Higher RPM without running a dry-sump.

Bearing clearance issues. Without the issues, Tony would rather sell you a std. pressure pump for max effort build. At least for me he did anyway.

Yea the oil pump is tricked out, with a unique bypass system using a internal hose to run the bypass oil right back to the pickup tube.
In the photo the pinkish nipple is where the hose connects and runs to the end of the pick up tube: They say it was meant to be better for higher rpm usage. I've got an older EMC magazine with the build and photos tried looking for it on the web so you can see how the hose is ran...Tricked out!
Build was a 436 lsx by SAM 775 hp as stated earlier. Tim *86 Hatchback also ran this pump with his 416/454 Ls3.

One aftermarket pump supplier has developed an innovative “energy-recovery” design for some of its Chevy LS oil pumps that reroutes a small amount of the pump’s output back to the inlet tube. Injecting oil back into the inlet tube creates a siphoning effect that helps prime the pump, improves oil flow into the pump, reduces cavitation and allows the pump to maintain a consistent output at higher engine speeds.

No one ever talks about their pumps, but i run a schumanns high volume with their proscreen pickup tube and i have been nothing but pleased. I also have no o-ring on the pickup tube to worry about

I would think Tony knows better than to make a blanket statement like that. People are driving 1000whp setups on the street and something like that shouldn’t be built with factory bearing clearances. Aluminum blocks are especially bad about pressure drops since they expand so much with heat.
