OWMTC 268/273SRlrSBC
3/8-5/8 tracks with wide corners or slick surface. 383+ c.i., 12:1+, 4 BBL gas or alcohol. Requires good intake and heads. 4/7 firing order swap. 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.

|---|---|
| • In 1987, GM began using hydraulic roller camshafts in Chevrolet Small Block V8's. Before ordering this camshaft, verify that your engine has a flat tappet camshaft. If your engine features a roller camshaft, look at our "08-" camshafts or "07-" camshafts if equipped with an LT1/LT4. | |

The industry-leading camshaft designers at COMP Cams set out to engineer a camshaft specifically for the requirements of open wheel modified racers. They had to take on the daunting task of building maximum horsepower, while still taking into consideration the tire restrictions, chassis technology, engine combinations, and common rule packages found in open wheel modified racing sanctioning bodies, such as IMCA. The Open Wheel Modified Traction Control Camshaft Series is comprised of 10 solid flat tappet and mechanical roller grinds for small block Chevys. These powerful camshafts are separated into four categories, each of which is optimized for open wheel modified racing. A combination of proven camshaft design technologies and the most innovative and aggressive lobe profiles in the industry has produced camshafts that deliver an extremely wide powerband, pulling hard off the corner and all the way down the straightaway. A further benefit of the broad horsepower curve of these cams is that they minimize tire spin, creating legal traction control. These innovative grinds have been extensively track-tested, and they have been proven to run faster than any camshaft that has ever been tested for this type of racing. COMP Cams OWM T/C Series offers a cam for just about every open wheel modified racer.
