Anyone know what Bearings are used in MTI forged 346's?
Also what bearing clearances are used in their assemblies normally?

Anyone want to comment on MTI forged 346's and idle oil pressure?

Am wondering how loose their standard bearings are vs. stock...
I believe Pecos assembled my motor.
Will call MTI Monday AM..

I believe my Oil Pump needs to be replaced and I may have a pinched O-Ring. Just wanting to confirm everything.

If they run looser clearances, what oil pump setup do they recommend? Couldn't find a high flow one on their site.

Ran into this thread during a search, but it doesn't have a resolution or reflect on 346cid motors:

When I talked to them they were using clevltie on the mains and cam bearings and Federal mogul's on the rod bearings. I didn't ask them what clearances they were using. You might just give them a call and ask.

Thx, will call Mon AM.

They said they do install their bearings looser than stock but don't give out the exact specs.
