Jon Kaase’s career as an engineer and engine tuner has a depth few contemporaries have achieved. On Monday, October 15, he celebrated his sixty-sixth birthday, and a few days earlier, he won his ninth award at the Engine Masters Challenge in Cleveland, Ohio. He felt privileged to have a chance to compete again and grateful for the new-found enthusiasm for the contest. More recently, he introduced a new big-block Ford cylinder head, the SR-71, his first in 10 years. • Raised intake entry ports • 100% CNC-machined in-house on 5-axis Hurco • Compatible with Super Cobra Jet intake manifolds • Fits all conventional engine bays According to engine builder Jon Kaase, his company’s new SR-71 cylinder head will out-power any conventional big-block Ford head. Extensive dynamometer tests have demonstrated average gains of 50hp and similar peak gains over best existing cylinder heads. In addition, the usable engine speed range is increased by a minimum of 500rpm. Kaase assures that the SR-71 heads will fit the conventional engine bay, and when installed on a maximum-effort 598cid engine, will produce over 1100hp and rev to 8,000rpm. Despite placing the intake port entries half-inch higher than customary, all Super Cobra Jet intake manifolds fit the new heads. Clearly, higher intake ports are desirable, providing straighter, faster paths for the air-fuel mixture to reach the valves. Raising them while preserving compatibility with conventional intake manifolds is achieved by extending the port entry face toward the valley area—the head is wider. On the exhaust side, dimensions are stock Super Cobra Jet / Kaase P-51. The entire CNC-machining process is performed in-house on...

By Freddie Heaney: Click here to view images of the 2018 Petit Le Mans at Road Atlanta. Road Atlanta, Saturday 13 October 2018: In a hardly credible ten-hour endurance race, the no. 3 Corvette C7 co-driven by Jan Magnussen, Antonio Garcia and Marcel Fassler became the 2018 GT Le Mans championship winner, despite finishing two laps behind the second-place no. 4 Corvette of Oliver Gavin and Tommy Milner, despite having not won a race this season, and despite almost succumbing to a crash while exiting the pits. Earlier, the car had been in contention for class victory, but with around two-and-a-half hours remaining, Garcia spun exiting pit road and struck the wall. For a moment it appeared their race was over. But implausibly the damage was repaired and the car returned to the track in ninth, three laps down, awakening a scenario where Ryan Briscoe’s no. 67 Ford GT could win the championship by finishing second or better. Brisco’s Ganassi Ford had been trailing the winning Porsche 911 RSR, co-driven by Nick Tandy, Patrick Pilet and Fred Makowiecki, but then Briscoe, who had pitted with 48 minutes remaining, was overtaken by the no. 4 Corvette while leaving the pits. His Ford, for reasons unknown, was unable to match the Corvette’s pace and later fell behind the two BMW M8s, eventually finishing fifth. Such was the sequence of events that secured the championship for the no. 3 Corvette. Its impressive consistency throughout the 2018 season brought eight podium finishes from eleven starts. Finishing third acquired further distinction for pole sitter no. 24 BMW M8 GTE of Jesse Krohn, John...
