The Edelbrock Rollin’ Thunder Camshaft #2213 for 273-360 CID Chrysler small-block engines is a high-performance hydraulic roller cam for street or strip applications. With an RPM range of 2,500 to 6,200 RPM, this cam has been dyno-tested to deliver substantial gains at the 4,000 RPM mark. The #2213 Rollin’ Thunder Camshaft produces a rough idle with an intake lift of .544 inch, exhaust lift of .541 inch, 286/294 degrees duration, 236/242 degrees duration at .050-inch lift, and a lobe separation angle of 110 degrees. We recommend our Performer RPM #60775 Cylinder Heads, #7177 RPM Air-Gap Intake Manifold and #1906 AVS2 Carburetor with this combination. Engine assembly lube included.
