My older 440 source 4.150 stroke crankshaft was turned 0.010 under before I bought the car. Putting the engine back together after the previous 'mechanic' assembly process resulted in a spun cam bearing and other misery... The speed pro 'narrow' bearings result in zero side clearance when installed on 440 source rods.
Anyone know the actual width of other 'narrow' bearings?
