Nothing about them on Jon's site, but then he's notorious for having a whole engine and all the "good" components developed and tested before he releases anything about the pieces!!! Same way he did the "Boss 9" engine, and many years before the Kaase CJ heads for the 385 engines.....

Here's an excerpt from this year's Engine Master's competition, dang good numbers from a 4 valve mod motor with no supercharger, nitrous, or turbo!!!!!

Our five top qualifiers drew lots at the AMSOIL Engine Masters Challenge banquet to determine the running order in final eliminations. Jon Kaase drew the kick-off position and was the first to run. His wild 409-cube Ford Cobra engine was going into the finals with a second place score in qualifying, and whether this proven Engine Master could find more in the MOD motor was anyone’s guess. The experienced crew worked the tune, taking advantage of the cold morning air. Every move poured more power into the mighty MOD – these guys could do no wrong. Power output now tagged 721 peak horsepower. Torque was off the hook, with 600 lb-ft at just 3200 rpm, peaking at an astonishing 675 ft-lbs. Kaase’s effort bumped his score a remarkable 45.2 points to 2961.7.


PS--the Tri-Y's were on the engine for the dyno runs.......hard to say without pulls with other headers what the power differences are. I'm sure Jon knows!
