Quick question on crank bearing installation My engine has been apart for a while now, the bearings have a notch to one side, at one end of each bearing half. I thought I remembered the notches being oposite of one another, is this true? A machine shop told me they should both seat connecting with each other, but in main #3 it looks like the only way to assemble it is with the notches opposite one another. Some quick help would be very appreciated, thanks
I believe the center bearing, one of the inserts can be installed either way. It has 2 notches in the block or the cap.
The important thing is the main caps have to go on the right way. The front 4 are installed with the nubs pointing to the back of the motor, and the 5th cap, the back one, is installed with its nubs pointing to the front.

lol oh yea you called that on the rod bearings 
on the mains I was just hopin for something a little more solid, but yuh know what I think your right about the main bearings being opposite one another, cuz thats how I started the post thinking and you kind of confirmed it so I think Ill go ahead and install them like that. The only thing that really threw me off was the machine shop telling me they went together- but what do they know (hopefully not much 
) ok Im gunna go put her together now, Ill letcha guys know if it blows up

If you put the main caps in the way they go, you'll see there's only one way for the bearings to fit. It's self-explanatory once you look at them. At least mine were on my 6.0L iron block.

i just ran into this crap today on my 6.0-the #5 main cap can only go in one way, and the bearing tangs are on opposite ends-1f 1-4 are put in with tangs together, they match up in design with cap #5 (it has 2 little indentations in the caps) never ran into this chit with s/b's. b/b's
wish i would have paid closer attention taking it apart-its just going to the machine shop anyway-so im wondering if the #5 cap is supposed to be diff in how the bearings match up, as opposed to 1-4?

this was buggin me, so i went back out tonight and took another look at #5 main cap, and noticed it had a cutout on each end for the bearing tang?? dont know why, but if the bearing half was just taken out and swapped, it would now match up-my guess is when the factory assemb. it, they had it switched, not realizing it wasnt matched up
