summit box is the same as Mallory 685
$220 compared to $260 for the Mallory.
I just bought a used one but if I was going to buy new I wouldn't hesitate to buy the summit brand over the Mallory to save a few bucks. I'm sure it's the exact same box just rebadged.
Anyone else seen it?
It's an ignition box like an MSD which ups the output of the coil. The Mallory actually puts out more volts than a 6A or 6AL
It has a window switch for nitrous
a 2 step
and a built in timing retard for nitrous, so you dont have to run around on a nitrous tune when you're not spraying. Timing is automatically pulled when you arm the kit.
Also has built in start retard if you had a high comp motor, retards timing 20deg on startup, makes it easier on the starter.
