A spin-off from one of our most popular 6.0L cams, the Rob Style JUNIOR is scaled down for a 4.8L or 5.3L truck. Our Rob Style cam sound-wise is in between the Stealth and Attitude camshafts. The lope is noticeable but not as loud as the larger Attitude camshaft, and we found it holds better gas mileage as well. This is a potent cam that drives well, gets great mileage, and can be used with the stock torque converter, or aftermarket. Tuning required. Dyno graph shown is intake, headers and tune, vs after pulls of adding Rob Jr. Cam and 102mm FAST Intake only. See this cam featured in a customer build blog – HERE!  Idle Video in 4.8L!
