    Street Cam Comparisons
    The following chart compares some street cam selections from afew manufacturers. I chose to include Racer Brown because ofthere long standing commitment to developing cam profiles specificallyfor mopars. I included Camcraft for the same reasons,Isky because their reputation, and CompCams for theirXtreme Engery line of mopar specifc grinds.Mopar Performance, was of course, not overlooked.Summit Racing was included because their cams are 30%-50%the cost of the competitions. After a little rearch I found thatthese are profiles that originated with Wolverine Cams for Smallblcok Chevrolet engines (Wolverine is now owned byCrane Cams). This list is sorted by lift.

    Note 1: SUM-6400 has the same profile as SUM-1103 andSUM-6401 has the same profile as SUM-1105. Both of these SUM-110?cams are Chevrolet grinds. For what its worth, Summit Ford grinds are unique to Fords.
