which bearings did you go with? not sure what other brand cranks for 400B are offered in the 4.150 stroke with 2.200 rod journals, but i may just go on price alone if i have to have the crank machined anyway. i dont think the main bearings for the B engine are offered in over sizes(thinner) like a +.001 for instance. that would have been nice.

I prefer an analog gauge, graduated to .0001. That way, I can see it sweep towards zero, and very easily take a reading off the needle, without having to digest a bunch of moving numbers. IMHO, .0001 is essential, .0005 is too vague. Totally agree. I do a lot of work with shops and teach them measuring. No one uses a digital one.

i must have either got luck or muscle motors cleaned it up. my machinest said my was really nice. I agree. And I said, I bought some additional bearings in + increments just in case I needed them at assembly. I didn't use them.

I have a Molnar rotating assembly for a 540" hemi out in the shop that we got from Dan at Performance Only. As far as I know, it needed no corrective machining and he spoke very highly of their products.

I wasn't able to find any 400 mains in +/-0.001" sizes. I used the chamfered Clevites that Hughes sells. Had to get a second set(0.010" under) when I couldn't get much more than 0.0025" clearance on the std mains. King makes a 400 main bearing, but they steered me to Clevites when I told them I'd be using a decent amount of nitrous. They said their bearings don't provide enough support for a nitrous application. To clarify....not ALL King bearings, just the series they offer for a low deck Mopar!

Yeah. King doesnt offer a full groove neither. Dave What about MB555AM king bearings, those are full groove for the lo decks.
