LS Engine Build - The Garage-Built LS Stroker, Part II

To give Lester a little luster, we dressed him up with a Kwik Performance alternator mount that eliminates the power steering pump. The kit bolts to the cylinder head and uses either a truck or LS1 Camaro alternator. Kits are available to work with a Corvette, Camaro, or truck balancer.

Test Data
Test 1 equipped the 404ci motor with stone-stock 6.0L heads and valves, adding Comp 26918 valvesprings along with the Edelbrock Victor Jr. cathedral-style intake manifold, a Holley 950 HP carburetor, a set of 17/8-inch chassis headers, and a pair of 3-inch Borla mufflers.

Test 2 used the same equipment except for the addition of a set of WCRCH CNC-ported 6.0L heads and the same springs.

Test 3 added a set of stock L92 heads along with the bigger Comp cam. The larger L92 intake ports also required an Edelbrock Victor Jr. L92 single-plane intake manifold. We retained the 950-cfm carburetor but added a 11/2-inch Wilson tapered carburetor spacer.

Test 4 added the GM Performance Parts CNC-ported L92 heads. The rest of the components remained the same as in Test 3.
