For street and some strip use. Works with points, magnetic trigger or GM HEI ignition systems. Has built in Soft-Touch Rev Control. The rev control randomly drops spark pulses to some of your cylinders to keep your engine at or below its maximum rpm. One the next cycle, those cylinders are fired to keep them from loading up with fuel. Adjustable rpm limit with 3,000, 6,000, 7,000, and 8,000 rpm plug-n modules, included.
