Eagle forged 4340 featherweight crank for Chevrolet 305/350 with a 3.500" stroke, built for restricted-class competition where minimized rotating weight is required. The featherweight counterweight design lowers mass; .125" fillet radiuses increase strength but require chamfered or narrowed bearings. The crank is nitrided and micropolished; lightweight rods and pistons are recommended to ease balancing.
