Description

This LS7 engine family utilizes a Mast Motorsports engineered camshaft that is custom ground on a Mast Motorsports 3 bolt cam core. The 427 SS’s foundation is a fully machined aluminum block with a forged Callies rotating assembly with Mahle pistons that is topped off with Mast Motorsports Black Label LS7 305cc cylinder heads and FAST LS7 intake manifold. ARP fasteners are used throughout and Mast Black Label pushrods ride on GM Cadillac High RPM hydraulic roller lifters. This hand built LS7 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.
