The specs for the summit box are actually better and cheaper than the MSD box. I've never heard of anybody using the summit box though. Would it be worth looking into or should I just find a 6A box for cheaper? It would be going on the truck in my signature. Thanks.
I have never heard about the Summit box. It would not surprise me though, if MSD actually made it. Someone makes it for Summit. Summit is like the Walmart of High Performance parts. If you have the power and the money, and put in a large enough order, you can get someone to make something for you at a reduced cost.
I really don't know who makes it though.
Summit doesn't make parts, it while labels other manufactures. It doesn't look like an MSD, the wire appears to be cheap PVC insulated and the mount bracket is in the white. I'd hope MSD would carry their standards over to their private labels.
