Summit multi-spark digital ignition boxes ... worthwhile?

Is there any advantage to running a multi-spark digital ignition in a street/strip vehicle? Summit offers their SUM-850600 (http://store.summitracing.com/partde...5&autoview=sku) for $169.95 (along with $15 Summit bucks) which seems pretty reasonable.

Specs:
Part Number: SUM-850600 Ignition Box Output: Capacitive discharge Circuitry: Digital Rev Limiter: Yes Timing Retard: None Data Acquisition: No CD Voltage Output to Coil: 520 V Current Draw: 0.6 amps per 1,000 rpm Spark Output (millijoules): 135 Millijoules Minimum Operating Voltage: 8 V Maximum Operating Voltage: 16 V Length (in): 8.000 in. Height (in): 2.750 in. Width (in): 3.500 in. Ignition Box Color: Black Coil Included: No Warranty: One-year warranty Quantity: Sold individually. Notes: Not CARB approved. This ignition box fits most 4, 6, or 8-cylinder vehicles with a distributor, and a 12-18V electrical system.


Since my '69 is a 5 speed, I really like the idea of the rev limiter. My goal is just to make the most of the engine I already have without great expense. I've read other posts on MSD boxes failing, but like some people have replied, other electronic parts may fail just as often. I'm just looking for opinions before I decide weather I'll order one or not. How would you compare this Summit unit to others (Accel, MSD, Mallory, Pertronix, etc)?

I'm running it and like it. I have almost 1000 miles with my new resto and no complaints. I haven't hit the rev limiter yet, but will this spring due to engine break-in.

Most of the time Summit has their parts made for them by someone else and they just put their name on it. More than likely, that box is made by someone like MSD or Jacobs. Call them and ask them who makes the box for them.

Re: Summit multi-spark digital ignition boxes ... worthwhile?

Ensure you DIODE the relays in your ride or use relays with diodes built into them, especially if you run electric fans as they will create EMF spikes and burn transistors in the MPC (Micro Processor Circuits) of the CD Module and Electronic Trigger of the Distributor. The old wiring of our rides were never designed to handle modern MPC; even then carry your old Points Dizzy in the trunk.

One thing I got to say about Mallory is that they have an excellent customer service and tech department and will repair their units after warranty for minimal cost.
