I ran an XC8 on a '71 Camaro for a while. I had to use the cable. It was a constant adjustment. But since you have a throttle rod, you are going to have to make your own rod using a piece of allthread since the factory rod has the wrong geometry. My father ran the same XC8 on a 1969 Z28 using allthread. You just need to cut a piece probably a foot and a half long, and bend it to fit your linkage. Do you have the tri bar assembly? You need this tri bar, as that is where the rod links up and operates the carbs. Good luck! Just keep in mind, once you get the linkage correct, you still have to tune it. It's like two manifolds. J
