Yes, thats why its called MSD 6a, by MSD Ignition. But its a big red box that is hard to hide on a car you want to try to make look stock. The Pertronix 71281 Ignitor III Adaptive Dwell Control for Multiple Spark with Digital Rev Limiter all fits under the distributer cap, and only has one extra wire that goes to the positive side of the coil, along with the standard ground (black) that goes to the negative side. Put them both in a black heat shrink tube and a casual glance will not be very obvious that it is even there. Pertronix advertises for the Ignitor III:
I currently only have the Ignitor II. No Multi-spark (aka MultipleSparkDischarge) , No REV Limiter. I'm just looking for the MultipleSparkDischarge/Multi-Spark though, with out the big red box.
Are you aware that your 6a box already does a multiple spark?
The MSD produces full power multiple sparks for each firing of a plug. The number of multiple sparks that occur decreases as rpm increases, however the spark series always lasts for 20° of crankshaft rotation. Above 3,000 rpm there is simply not enough "time" to fire the spark plug more than once, so there is only one powerful spark."
I've got an auto, so not as interested in the Rev Limiter as I am the Multiple Spark Discharge feature. The 3 has it, the 2 does not. Majority of that I have read people say adding the Pertronix adds a new life to their motor. Pertronix states the 3 works best on Big Blocks with big cams. I'm running a stroked 351W (418ci) with CompCam's Magnum 280H. Big cam for the 351, but the extra cubes are going to tame it a little.
I guess it depends on how much you desire the rev limiter in the distributor? I don't have that feature on my three vehicles, although my 6AL boxes do have the option. I've just never used it myself.
I've used Pertronix on several cars, and really like them, so I'd probably keep it and use it.
I bought this for around $100 over a year ago. Now I find the Ignitor III on Amazon for $98. I understand the 3 has MSD and a Rev Limiter. Should I take the loss and upgrade to the 3 for the MSD? I still have my "MSD 6A" box. How nice that you can get that feature now and put it all under the stock Cap!
hey Red, how did that Nova slip into the show? LOL
Just got back from a local Car Show here in Miami. Took a few photos but too many to try to post here. Photo Album <-- Click there to see the cars (mostly newer Mustangs)
That's great video footage Vall.I am going try and get some video footage of testing when i get the car back from paint shop prizon.
A friend of mine sent me the link to this video recently from the Billetproof Drags at Toutle, Wa. The 2nd race shown is my '63 Falcon against my buddy's '56 Chevy gasser. I got a little air under the front tires at launch, but the jersey barrier blocks the view.
Nice engine change to the Hemi! That's such a nice upgrade, even if it didn't make any more HP, it would still be the wow factor it has!
