Summary:
The 600 Performance Road & Track Engine 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 CP pistons that is topped off with Mast custom cast LS3 heads and an LS3 intake manifold.  ARP fasteners are used throughout and Mast hardened pushrods ride on LS7 hydraulic roller lifters.  The 600 Performance Road & Track Engine is the second 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 Performance Road & Track 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 manners for a daily driver.
