Product Description

The LS3 416’s SS 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 3 bolt 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 Turnkey Crate Engines that are designed for the Hot Rod/Muscle Car market.  The LS3 416 peaks at the 600+ horsepower mark and is competitively priced for such a powerful complete fuel injected turnkey crate engine. 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.

 Package Includes: Mast handbuilt 416 LS3 and MAST Motorsports M90 ECM and engine wiring harness. 18 Month Warranty
