Edelbrock Chevy Gen 3/4 Ls Victor Jr Cylinder Head - Lsx Block

The Edelbrock #61349 Victor Jr. LS3 cylinder head emerges as the optimal choice for high-performance street and competition engines that have maxed out the potential of stock-style cylinder head designs. In contrast to many aftermarket LS3 cylinder heads currently available, which often rely on enlarged ports within a stock head design, our Victor Jr. LS3 cylinder head takes a revolutionary approach with an entirely new design from the ground up. This design incorporates subtle yet impactful changes aimed at enhancing flow and combustion for elevated performance levels.

Notable alterations include a 2.20" diameter intake valve configured in a canted orientation, reminiscent of the GM LT1 Gen V engine. This shift in the intake valve, coupled with a distinctive port shape, results in nearly 400cfm peak flow. The cylinder head is further refined with fully CNC'd intake ports, combustion chambers, and exhaust ports, ensuring consistency and improved overall performance. These modifications collectively empower the cylinder head to achieve 600+ hp on an LS3 engine, even with stock rocker arms, intake manifold, and exhaust manifolds in place.
