I have a 340 block. The crankshaft has been turned .010 and polished. Bearings installed in the block and the mains torqued. Inside bearings measured against the crank dimensions and across the block all mains have 0.003 clearance. Install the crankshaft, torque the main studs and the crankshaft will not turn. Removed the caps install caps one at a time torque the main studs and the crankshaft will not turn with only any one cap in place. What am I missing here? Have not measured inside the caps before installing the bearing but if it has a consistant 0.003 clearance on each bearing I would think there is not a problem with the bearing thicknesses. Align hone the block? All suggestions are welcome we are just missing something here.
