Crankshaft Alignment to Block

[tennsmith]

Long story, but I'll try to be brief. The end objective was to align flywheel housing to the crank flange and measurements here showed a 0.010" difference between sides..9 oclock being high and 3 oclock being low. I figured my flywheel housing was warped.....or the crankshaft was not perpendicular to the block. Put the dial indicator base on the block and indicated/rotated the crank....less than 0.001 on that one, so next I put the dial indicator base on the crank flange and the dial pointer on the rear flange of the block and swept it 180 degrees...0.010" difference!!! What has happened here? Bad alignment of the babbit main bearings when poured or line bored to size? The guy I bought the engine from said the babbit was "original" and all he did was remove shims to take up some of the excess clearance. As luck would have it, I need to shim the housing on the side where the cam hole is in the block, therefore shims here are a certain leak...particularly 0.010 worth. Anyone else experienced this problem? Any known repair solutions? Options?

Thanks,
