Description

This LS 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 Diamond 2618 pistons that is topped off with Mast Motorsports Black Label LS7 305cc cylinder heads and a Hillborn fuel injection system. ARP fasteners are used throughout and Mast Black Label pushrods ride on CPP 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.
