In a final-5 showdown that pitted a pair of Chevy LS engines against a trio of 4-cam Ford Mod motors, Jon Kaase Racing won the 2013 Amsoil Engine Masters Challenge.

Information that EngineLabs gleaned from the Engine Masters website and various team and supporting company Facebook pages indicates Kaase’s 409ci engine pulled 721 horsepower with 675 lb-ft peak torque to score 2961.7 points. That was almost 45 points higher than his qualifying run that had put the veteran engine builder second in the preliminary standings before the Friday’s finals.

The best-scoring LS engine came from the School of Automotive Machinists (SAM).

The leading qualifier was Accufab, which pulled 736 horsepower and 664 lb-ft torque with its 401ci Ford. That was good for 2938.5 points to lead the field. But in the finals the power levels slipped to 734 and 661, respectively, leaving the team with 2931 points and second place.

A Ford also took third place as BES Engines reinforced its third-place from the qualifying round. There it scored 775 horsepower with 632 lb-ft torque for 2867 points. The team tried adjusting the cam timing final with no success, scoring 2863 points.

Rounding out the competition were the two LS engines from School of Automotive Machinists and a second team from BES. The SAM Racing crew, which won last year with a Chevy SB2 powerplant, brought out a new 436ci LS and pulled 775 horsepower and 677 lb-ft in the preliminaries to earn 2844 points. Numbers for SAM’s final runs weren’t posted, and the team did move up to 2,858 points, but it wasn’t enough to score a podium finish. The other BES team had a 401ci LS that was fifth after the qualifying. In the finals the Also BES team moved up to 750 horsepower and 625 lb-ft but couldn’t overtake SAM.

The Freelander Race Engines/Oakley Motorsports team built a 572ci Ford FE that twisted the dyno for 870 horsepower and 815 lb-ft torque — best of the competition.

In the end, Kaase’s Ford didn’t make as much power as the two LS engines but boasted a much stronger torque curve for its size, and that performance factors into the points total.

The week-long competition saw nearly 30 teams fire up their bullets. A 572ci Ford big-block engine scored the highest readings during qualifying with 870 horsepower and 815 lb-ft torque. However, the points system factors in engine displacement, so the big FE didn’t qualifying very well with just over 2,500 points. A wide variety of engines were represented, including small- and big-block Chevy, Pontiac, Gen III Hemi, Buick, Ford Boss and Cleveland, big-block Mopar and even an AMC.
