Powering John’s green giant is a Chevy 410ci small-block equipped with forged pistons, ported Chevy heads, a full roller valvetrain, and a Lazer camshaft. The beast is fed by a Holley ProJection four-barrel EFI system mated to an Edelbrock Performer RPM intake manifold. The fumes exit through a pair of Doug Thorley headers that connect to a 3-inch Magnaflow exhaust system. Spark comes from a Jacobs electronic ignition system. The mill is cooled by a Be Cool aluminum radiator.
