This Eagle cast crankshaft is a one-piece standard crank for Chevrolet 305/350/383 engines with a 3.75" rear seal journal, offered in cast steel. Built with .092" fillet radiuses to increase strength while retaining compatibility with OE replacement bearings, it’s recommended for pump-gas, naturally aspirated road cars rather than competition applications.
