A similar cam to the 188-220, but with more lift and slightly more duration on the intake. This cam will work well if you are looking for a little more airflow than our 188-220 will provide. Works well from 1800-4400rpm. Must use performance valve springs and pushrods. Install on 99 degree intake centerline. If you have not surfaced the head or block it will drop-in in most instances. Always, degree the cam and check piston to valve clearances.
