Magically increasing bearing diameter

All main caps and saddles (the block side), and rod and rod caps have a bearing keeper retaining tabs in them (they look like a little notch, if you will), always remember kepper retaining tabs always go on the same side facing each other, regardless of where they number are stamped, they were more then likely stamped someone who rebuilt the engine before you.

Here's what I do when I'm assembling a engine, of course I would start with installing the crankshaft, main bearings and main caps, I normally start with the center main, each time I install single main cap, I torque it down right then and check to see if I can turn the crank by hand, then go onto the next main cap, torque it, turn the crank, then on the installing the rods and piston, folowing the same routine torque each one as I install and torque, and then turning the crank with each component installed, that way if something binds I know exactly what it was, the last thing I installed. Building engines is all about sequence, and checking after each step.
