BUGPACK CAMS
Make no mistake, choosing the correct camshaft for your engine is the single most important selection you’ll make in building your engine. That is why you should go with a proven winner – like BUGPACK! Our new cam profiles are very carefully designed to insure maximum performance including features like lobe center and lobe shape, which can make or break a camshaft’s performance and drivability. Check out the new specifications, applications and group characteristics to help you select the perfect cam for your engine combo. Lift dimensions supplied are measured at the valve using the appropriate stock 1.1:1 ratio rocker or aftermarket 1.25:1 and 1.4:1 rocker arm set. Camshafts are shipped with break-in lube and timing/info tag. Cam gears and lifters available separately.

NOTE: All BUGPACK cams must be installed using new BUGPACK lifters. Other lifters may not be compatible due to variations in heat treating, alloy used, or the radius. Failure to do so greatly increases chance of failure and as such cannot be warranted.
All cams used in ’71 and later applications require a pre ’71 style oil pump assembly.
