"Talk is cheap. We wanted a graphic demonstration and some hard numbers to back up the babble. For that round, we went to Glen Elsberry and a 351ci LS1-block-based engine that he'd taken fresh from the dyno cell. Glen arrived at the displacement with an HTC Budget Kit featuring a 0.010-inch overbore and a 0.030-inch-longer stroke (3.905 inches). The Speed-Pro hypereutectic pistons were installed 0.005 inch above the deck surface and cohabit with some port-tweaked 5.3L cylinder heads. The compression ratio is about 11.0:1 with a 63cc combustion chamber that Glen massaged to meet the outer limits of the bores.
Elsberry poured the bumpstick to his LS1 freak: a GM ASA road-race cam (0.525-inch lift, 219/236 degrees duration) with corresponding valvesprings. To feed the thing, he plopped on an LS6 intake manifold, attached an 87mm throttle-body, tapped in 30-lb/hr fuel injectors along with a 60-psi Mallory fuel pump, and used an ambient air temp sensor rather than the MAF. The primary pipes on the special dynamometer headers were 17/8 inches in diameter. Fuel was 91 octane. With the mild ASA cam, the gritty LS1 produced 479 hp. The torque curve was flat from 3,000 rpm."
