Handbuilt LS engines feature the best components and are assembled by professional machinist. All handbuilt engines feature ARP Main Studs, ARP Head Bolts and a balanced and blueprinted block.

This 402 cubic inch engine has a race engineered camshaft that is custom ground on a 3 bolt billet cam core. The 630 Performance Race Engine's foundation is a honed and decked LS2 aluminum block with a 4.000” forged Callies rotating assembly with Diamond 2618 Alloy pistons that is topped off with CNC LS3 heads and a GM LS3 intake manifold. ARP fasteners are used throughout and hardened pushrods ride on GMPP High RPM hydraulic roller lifters. This hand built LS2 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 to occasionally drive it on the street.
