Description

The LS3 416’s heart and soul is the new 4.065 aluminum block. The LS3 designation has a Mast Motorsports engineered camshaft that is custom ground on a Mast Motorsports LS3 cam core. The 416 foundation is a honed and decked LS3 aluminum block with a 4.000” forged Callies rotating assembly with Mahle pistons that is topped off with Mast CNC LS3/L92 heads and a LS3 intake manifold. ARP fasteners are used throughout and Manley pushrods ride on LS3 hydraulic roller lifters. The LS3 416 is the first release of a diverse line of Mast Motorsports hand built LS3 based "Drop In" Crate Engines that are designed for the Hot Rod/Muscle Car market. The LS3 416 peaks at the 575+ horsepower mark and is competitively priced for such a powerful complete fuel injected turnkey crate engine.
