Check the main bearing bore for misalignment. There are several methods to do so. It is easiest to use a straight edge and a feeler gauge. Use a blade half the thickness of the maximum clearance. The feeler gauge must not fit between the straightedge and the surface of the bore. Oversized bearings compensate for the amount of material removed during the machining process.
As you might expect, undersized bearings see use for the exact opposite reason that oversized bearings do. While line-boring a block isn't usually necessary unless the engine's spun a bearing or the builder wishes to assemble a perfect creation, crankshaft machining is much more common. Crankshaft journals bear the brunt of your engine's horsepower assault and are subject to all sorts of damage and wear. Journal scoring or scratching as a result of oil contamination is common.
To restore the journals to stock smoothness, machinists remove just enough material from the journal surface to eliminate the deepest scratches. Undersized bearings compensate for the amount of material removed during this machining process. It's thicker and takes away 0. One one-thousandth of an inch is a big jump, but you can actually make adjustments in 0. To do this you mix half the shell of a one-over or one-under bearing with half the shell from the standard bearing.
This means you may have to purchase a couple sets of bearings to get everything just right in your race engine, but sometimes that's the price you have to pay. Just remember when mixing shells to always keep the sizes in the same alignment. In other words, if you're using one-unders with standards for your main bearings, put all the one-unders in the cap with the standards in the block side of the housing bore, or vice versa.
So with that said, let's get on with it. One of the most important factors when it comes to the health and durability of your rotating assembly and the block itself is the amount of open space between the main and rod journals on your crankshaft and the bearing shells they are spinning within.
Problems can enter the picture pretty quickly when the bearing clearances aren't correct.
