Joe Carroll is a veteran AMSOIL Engine Masters Challenge competitor, favoring the small block Chevrolet engine. This year Carroll’s small block measured 401 cubic inches and featured a set of Australian manufactured Racer Pro cylinder heads topped by the more typical Edelbrock intake manifold and Holley carburetor. The small block was well set up for this competition, having a fat overall power curve. The engine produced 644 peak horsepower and 602 lb-ft of torque. Scoring the qualifying pulls yielded a tally of 2703.1. Not quite enough to catch the leaders, but a very good score from Carroll.
