This 416 has a Mast Motorsports engineered camshaft that is custom ground on a Mast Motorsports 3 bolt cam core. The 416's 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 Black Label LS3 heads and a LS3 intake manifold. ARP fasteners are used throughout and Mast hardened 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 Turnkey Crate Engines that are designed for the Hot Rod/Muscle Car market. This hand built LS3 based engine utilizes a camshaft that has a strong lope that creates great mid and high RPM power for the customer that will be aggressively racing their vehicle, but still wants great street manors for a daily driver. Runs on Premium 91-93 Octane.
