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.

Totally agree. I do a lot of work with shops and teach them measuring. No one uses a digital one.

Ok. Are the shars dial indicator any good? Which is most accurate a .250 dial or a .125 dial both with incerments of .0001?

one will be just as accurate as the other regardless of travel length.

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.

not much of a selection here for the lo deck, but i'm leaning toward the molnar crank and rods. second choice would be 440source. thanks guys

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.

King told me they do not have a performance bearing in a full groove for the 400 block. So that full groove you mentioned must be a stock replacement bearing like the 4094m federal mogul.

I bought Molnar crank and rods for my engine last summer. I was very impressed with them both. All main and rod journal were .0005" under sized (for extra clearace I'm guessing), but they were all the same, zero taper anywhere. Only thing that I had to do to the crank was balance it, and it didn't take much to do that.
The rod bushings were sized correctly out of the box (unlike the previous set (differnt mfg) that I bought that the pin wouldn't go into at all, another trip to the machine shop and more $'s)
If I were going to buy a crank today, my first choice would be Molnar.

ok. iv got it narrowed down to molnar than 440 source. source has an ultra lite 4.250 lo deck crank if i go that route.
