whats better 6a or 6al

The 6al is nice not just because of the rev limiter but because there are so many options to choose from if you need them later on down the road, such as a timing retard switch, two step or three step box, rpm activated switches for shift lights, and the list goes on. I got the Mopar Performance ignition box which is a MSD 6AL with Mopars name on it. I sell them all, the 6A is $204.47 the 6AL is $249.99 and the Mopar Performance box is around $235.00. "I'm not looking to make a sell I just wanted to give you a reference point to go by for prices."
