Mechanical flat tappet camshaft for oval track applications by COMP Cams. Cam features a 4/7 swap firing order (18736542 firing order) which exchanges the 4 and 7 camshaft lobe timing in small block Chevy V8s. This provides a a smoother application of force to the crankshaft. Some 4/7 swap engines will experience horsepower gains but all of them will gain an exceptionally smooth torque curve with this new firing order technology.Cam Application Chart (GIF)282-1268847 Specs (Link)
