    so as many as you already know, chevy changed the firing order for v8s from 18436572 to 18726543... did chevy just label the cylinders differently and now the reference is in a differnt location? anyone know more on this topic?

    A change in the ignition firing order requires a different cam since the valves have to open at different times and normally a different crank shaft though there are a few odd exceptions to that ive been told(something about swapping 2 cylinders igntion and cam timing for more power with same crank on some engine that I forget).
