That 509 cam might not had been the best choice for street performance, but it sure sounded like it was! That bad boy gave the motor a sound of its own.

Like a lot of stuff back in the day, the performance level highly depended on the guy doing the tuning. Some guys had the touch, and others pretended they had the touch. It seemed as though the guy with the touch could make any combo work, and the guys without the touch might have ended up with one combo that worked pretty well, so they stuck with it.

If you really want performance, I'm not so sure any of the old cams would stand up against the newer stuff, but if you want to look and sound the part, the old stuff is hard to beat. Gene
