Eagle cast crankshaft for Chevrolet 305/350/LT1 applications is a one-piece, internally balanced crank with a 3.750" stroke and a 1-piece rear seal. With .092" fillet radiuses it offers increased strength over some OE units while remaining compatible with standard replacement bearings. It's recommended for pump-gas, naturally aspirated road cars rather than competition use.
