Description

The LS7 HO’s heart and soul is the new GM Performance LS7 aluminum block. This LS7 engine family utilizes a Mast Motorsports engineered camshaft that is custom ground on a Mast Motorsports 3 bolt cam core. The 427 HO’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 285cc cylinder heads and a LS7 intake manifold. ARP fasteners are used throughout and Mast Black Label pushrods ride on GM LS7 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.
