This cam is by far our most popular street/strip cam for 455-474ci engines. The name came from all the dyno testing we were doing on different combinations, this cam works so well in so many different applications we started calling it "Old Faithful" and the name stuck. It provides a healthy sound at idle but really has a split personality as you can literally daily drive it but when you squeeze the throttle it'll pull till 6000+rpm in a heart beat. It supports power accessories and in our opinion (as well as a lot of customers) provides the best balance between daily driver street manners and track performance. This cam coupled with one of our aluminum CNC ported head packages etc. produces an awesome 550+hp 600lb/ft of torque street/strip package. Power range is 2500-6000rpm.

In a recent dyno test this cam installed in a 468ci engine with 9.5 to 1 compression, a set of our 260+cfm 6X heads, fully prepped cast iron Q-jet intake and a prepped Q-jet made 509+hp and 575+ lb/ft of torque on 91 octane.
