The mule for this test was a mostly stock Vortec 350 that had been sitting in an algae-covered four-door Nova for the last seven years. After pulling the pan and heads to check for critters, it was declared sound and ready for service. An MSD 6AL2 and matching Pro Billet distributor were borrowed from a 327, and the headers were typical 1⅝-inch swap meet specials. The custom COMP Cams hydraulic roller (with 226/239 duration at .050 and .521-/.554-inch lift on a 113-degree lobe separation, installed at 109-degree intake centerline) was from an old nitrous 383 small-block, but hey, it fit.
