THe cm-1 cam made killer power, i will say that. My car has a 4.10 gear and about a 4000 stall. Honestly, my car needed a higher stall and probably a 4.56 gear to make that cam work the best. Even so , the car ran in the 10.70's at the track. The CM-1 cam just didnt have a great idle and didnt have great street manners in my book. But i know streetability means different things to everybody. Im sure in a 500 cube motor, it would be more street friendly.
