PRODUCT DESCRIPTION
Similar to the infamous Mopar 284/484 Purpleshaft, this cam offers great street/strip performance with strong mid to top end power - 2500 to 6400 rpm power band. We recommend a minimum of 9.5:1 comp. ratio, a 4.10 axle ratio for RB-Engine applications along with a 3000 or higher RPM stall speed for auto applications. This cam will have a choppy idle. For use with multi-groove valves.
