Yes. Clamp time on the points (dwell) won't matter with the MSD as it gets it's trigger only when the points open. The MSD take care of charge duration (actually, there really isn't, as the capacitor in the MSD does most of the work for the coil anyway)

I put one together @ cost for ~$150

Yes, you're right. Clearly.

If you can get a even fire one,(78-83) it is a very simple process to convert it over. New pickup and cap, covered many times on many sites. Pickup about $15, cap about $20 and the cost of the dist. Or find a complete one out of a 75-77 odd-fire 231. They still sell complete reman units also as mentioned above. The default when buying parts is the 75 Buick Appolo with a odd-fire 231. Also to note that no grinding is neccessary when using a aftermarket aluminum intake and a button-head bolt.

Because when I replaced my crappy prestolite distributor, no one one could tel me squat about the HEI and no one knew anything about pertronixs. My dual point Mallory was $119 and my MSD back then was $89. The factory distributors may be prone to a lot of wear and maintenance but my dual point has not been messed with in 14 almost 15 years years now. I have a Delco with a burnt Pertonixs and intend some day to replace the unit but for now my points and MSD work fine.

But how many miles? For me 15 years would be about 80-85K miles.

Somewhere around 16-18k miles. My points don't resemble stock points in any way and are quite a bit more robust.

Yeah, I know. I used to run a Mallory dual point on my '72 Chevy truck.

I've been tinkering with jeeps and hot rods for well over 40 plus years.
I swapped to HEI a few times on a few builds, but trying to keep my jeep simple and easy to fix when (F.O.R.D.) has always been the issue.
I'm a firm believer in points and a Excell coil if I wanna a hotter spark. (my 2 boys call me "old school", but hell it's worked well for 100 years like that).
My jeep fires as easy and runs with the stock coil and points as it does with the excell coil, yeah once a year I change them, maybe check the dwell a few times, but I've never had REAL problems witha point set up, (that I dind't cause).
(I had to swap out the coil on my '61 CJ5 after I dropped it and made a good dent in the side). (I keep my coils away from the engine heat when I mount them)
My last jeep buold before trhis one, (a small block Chevy powered CJ7), I really could not tell the difference when I swapped out to a HEI. (short of a lighter wallet)
It still fired the same, ran the same, seat of the pants same power, etc. (I guess)
I'm SURE it was a happier engine with more powerful spark, took less time to fire in the cold, damp days.
I guess it IS personal perfernce, but replacement parts availabilty and more imporrtanto-cost would be my consideration.
But, that just me...........

It's a jeep, it's supposed to be simple.

Are you talking about Accel (the brand) coils? Or is there another one I haven't heard of?
