New class in competition category for 4 cylinders engine in

Charles Stewart · 12-24-2023, 11:26 AM

Change with the creation of the new L/D and L/DA class for the 4 cylinders 4 valves at 7,50 pounds, 850 pound minimum weight
(F/D and F/DA 4 cylinders, 2 valves engine only, 7,00 pounds per cu.in. 850 pound minimum weight. That part of rule staying the same).

Is this something that is actually happening or something you would like to see? I think it is a great idea. I have been hoping they would add classes for more modern 4 valve OHC engines. Thinking it may get some of the import, NMCA, etc, racers to compete.
