The OWM T/C Series offers a Cam for just about every open wheel modified racer. With the newest lobe designs, a nice broad torque curve with great power and reduced tire spin, what open wheel modified racer wouldn't want to try out this legal traction control? COMP Cams has taken Camshaft Technology for open wheel modified racers into the next century with the introduction of the OWM T/C line. But don't take our word for it - pick one up and see for yourself. If rules allow a Solid Roller valve train set-up, these 4/7 firing order swap cams are the best choice for power and durability. With four specially designed Camshafts to fit most popular engine combinations and track conditions, every open wheel modified racer can benefit from this breakthrough Cam Technology. These cams deliver a gentle torque curve for ease in hooking the chassis up, yet will not run out of horsepower on the top end. Designed for Race Series Valve Springs, Endure-X Solid Roller Lifters and the latest valve train component Technology, the COMP Cams engineers have designed the ultimate Camshafts for local and Big money open wheel modified Competition. This Cam is absolutely not IMCA legal! SBC - 1955-57 models have an oiling groove in the rear journal. The listed part numbered cams will not fit these models, so if you require a Camshaft with the oiling groove, please call us and we will assist you with placing an order.
