Eagle lightweight forged 4340 steel crank for Chevrolet 305/350 designed for restricted-class competition where reduced rotating weight matters. The non-twist forging and lightweight counterweight layout cut mass; .125" fillet radiuses demand chamfered or narrowed bearings. Nitrided and micropolished surfaces improve wear resistance; lightweight rods and pistons are recommended for easier balancing.
