good luck , low deck bearing selection is like 383 piston selection ... it sucks ...
Yeah, that's the truth, but then, for just one moment, there was a stroke of luck with the availability of the Sealed Power 3/4 groove. I guess luck ran out because it looks like they discontinued them. Wish I knew this stuff ahead of time
I figured with the popularity of 383 and 400 block strokers that the market would support this type of bearing, but everybody must favor the full groove I guess.
Gee, guess I need to become independently wealthy so I can buy up all these parts I want before they disappear off the market.
Guess I was hoping that maybe, just maybe, there was one or two sets kicking around the country somewhere on the back shelf of some wharehouse. The parts guys say no, they're not listed so they're not available.

Update: Okay, well it all started when I read in Andy Finkbeiner's latest Max-Performance Big Block book that one vendor was offering 3/4 groove main bearings for both B and RB blocks. This was at the time of the books writing; 2009. So when Summit Racing's online application guide listed a Sealed Power 3/4 groove bearing for the B-bock, I thought this must be it, another option besides full groove. With a little more internet research I found the online Federal-Mogul catalog and looked up the bearing P/Ns. With the actual bearing sizes listed (not found at Summit Racing) I discovered that the Sealed Power P/N 4924M is for RB applications. Summit's application guide lists them for both B and RB applications, which I guess is partly true if one were to bore out mains on the B block to fit the RB bearing size. So unless I'm missing something, the main bearing selection for Chrysler B-blocks is full groove, full grove and full groove. And all this controversy over nothing ![](/ubbthreads/images/graemlins/flame.gif)

Try search engines for old part number, sometimes you can find stuff that way, or even Flea Bag. Rock auto etc.They can't have ALL got used up?
You know, one would think that if a 3/4 groove B-block bearing really did exist at one time, there would be a copy or two collecting dust on a shelf somewhere. I've been looking high and low, but it would help if I had a manufacture and P/N # of this said bearing.

To my knowledge there's never been a 3/4-groove low-deck main bearing offered. Everyone I know w/ a B-block engine runs a narrow full-groove bearing since the only other option is a 1/2 groove.
The RB engines have always had a wider option for bearing styles & materials. I do run the 3/4-groove FM tri-metals in my 440s.
Who makes a 1/2 groove low deck bearing? I'd go with a 1/2 groove if I could find a set.

Half groove would be any stock replacement set what size do you need? I stock most of them
