Get what you want, you've already made up your mind. Doubtful you will notice ANY difference over a correctly curved Chrysler ign. with a good box, except that your wallet will be a lot lighter.
What people are trying to tell you is not that the Chrysler ignition is just "okay", but that there are few if any systems that are an improvement. As I said before, the HEI is a good ignition and I'm not dissing it- but what you have is already every bit as good for your purposes.
If you're just looking to spend money, go this route:
Hunt H2 All MoPar V8 's Internal Coil Rare Earth Magnets 4 amps
You can arc weld with it.
