The foruth day of competition at 2013 AMSOIL Engine Masters Challenge presented by Popular Hot Rodding magazine is sponsored by the School of Automotive Machinists (SAM). With Judson Massingill and his team of top students, SAM has been competing at Engine Masters Challenge since 2006 always finishing high in the ranks and taking the win twice. They’ll run last today and we expect an equally impressive performance from this year.
Thursday’s qualifying eliminations were kicked off by legendary engine builder Ron Shaver running a GM LS engine. The build featured an RHS block and Heads, displacing 427 cubic inches. The late model engine was equipped with a Holley carburetor on a single plane intake manifold. Shaver’s engine was clearly a well-developed piece, running flawlessly in qualifying. The power output was outstanding, with peak output recorded at 738 horsepower and 653 lb-ft of peak torque. The engine’s score was hurt by a dip in the torque curve right at the bottom of the rpm range, but the final tally of 2720.4 was enough to put Shaver among the leaders.
