MSD or not

I ditched the 20 year old Mopar Performance ignition last summer for a complete MSD setup (Digital 6AL box, billet distributor, plug wires and coil. I got the black box and distributor. I was AMAZED at the improvement. Starts are now instantaneous. One tap on the gas to set the choke, and then the engine starts instantly with the turn of the key. Plus it idles better and has better throttle response.
