Summit ignition box

As would I, but I don't know and I'm not giving advice based on "I DON'T KNOW".
Exactly!
I know. I use a factory ignition too, with GREAT success, but 1). The OP didn't ask about factory ignition and 2). I'm getting tired of arguing in favor of it when people don't listen so I'm ALL FOR whatever he wants to do, he just needs to verify.
