Description

The Scat 435007-3 Superlight 4340 Forged Crankshaft is a high-performance component designed for Chevrolet 350 Small Block V8 engines with a 2-piece rear main seal. This crankshaft features a 3.750" stroke and is manufactured from non-twist, single-plane 4340 forged steel for superior strength and durability in racing or high-performance street applications. Its "Superlight" design incorporates pendulum-cut counterweights, lightening holes in all rod journals, and aero wing counterweights to reduce rotating mass and oil windage, promoting quicker RPM response. Precision ground, heat-treated, and nitrided, it offers excellent wear resistance with large radii on all journals.
