The engine was dry and tight from sitting, so I took it apart. This is the crankshaft from a 63 Wildcat, 401/ Inflow, that had been sitting in barn untouched for over 40 years. The original bearings were attached, so never machined. This fits 59-63 Buick 401 engines that are attached to Inflow transmissions.
