A 100% New GM LH6/LC9 5.3L engine that Fraser has gone through and installed a performance camshaft package in. We also deleted the AFM/DOD for this engine. If you intend on using this for an application that utilizes the AFM/DOD, this must be turned off in the ECM. This engine will come with the valve covers and timing cover, NO OIL PAN OR PUMP. This is an all aluminum engine that is known for its extra thick cylinder sleeves. These are limited production, only 50 of them will be sold. *Dyno figures are based on using a 750CFM carburetor and Vic Jr. intake manifold with 1 7/8 headers. With an EFI system this will pick up power.
One-time guaranteed replacement, regardless of the cause of failure.
