I finally pulled the trigger on a complete MSD ignition system (box, coil, distributor and wires), and it came today. Summit had a sale and it was only $640. I plan to bump my cam a bit and add EFI later, so I thought I would do this first. The Mopar Performance electronic ignition (orange box) I have works fine, I just thought I would upgrade it first. I will probably sell the current ignition system when I put in the new one. I will soon see if the claims to improved idle and crisper throttle response are real.
