Hung Like a Stang

So I want to get some sort of multiple spark discharge box. But I don't know which one. anyone ever heard of a Mallory IVA, I've tried to do research on it. It's more expensive than mallory's VIA, it says it gives a more uniform spark throught the entire rpm range.

What all do you guys run? What have you been happy with?

Mallory and MSD have both taken me into the 8's so they are both plenty capable. Alot more people run MSD for some reason.
