Im about to put a new ignition on my 91 vert.Im ordering the Crane HI-6S ignition kit from summit. It comes with a PS91 coil. Have any of you used this kit before? If so what kind of improvement does it offer? The car is pretty much stock right now. Any help would be greatly appreciated

 

Never used Crane, but MSD makes some of the best ignitions you can buy. This is an area where you really do get what you pay for. I tried a budget Mallory ignition, and had to return it because it couldn't keep the fire lit above 4k.
