MSD 7AL 3  

I used to run that ignition with no problems. However, if you are buying new, I suggest stepping up to the “Grid” system. The AL series will be obsolete someday as MSD is gearing all R&D to the Grid.
Using the Grid, I was able to pull timing out of one cylinder to more evenly balance the EGT’s.
I am also able to load up different timing curves for differing track conditions or just to slow the car down.

Met up with a buddy last summer with a GRID in his boys blown mustang. I was amazed at what you can do with timing control and picking one cylinder? He has an issue with burning ring lands and was able to pull timing in that one cylinder and make the engine survive all summer. He was showing me on his laptop all the graphs.

I thought I was in high cotton when I replaced my dual points with a Mallory unilite conversion years ago LOL!! I still have my mechanical tach though.

Thanks, Jeff & Larry for the recommendations After reading them I've spent 2 days reading & watching youtube
what I could find out about power grid system "mind boggling" what It's capable of. With my small ci.motor,
Not sure if I would benefit from all it does? Unless, there was A "MSD Gooru" that gave 101 Ignition setup & execution for dummies,LOL
Hey Larry, I had to laugh two wks ago I was holding my old corvette duel point, Thinking how easy A fresh
set of points would be 🙂

mdunn, you mentioned MSD training. Here is a link from the yellow bullet on that exact topic. I have not taken that class, and it does cost a few $$$$, but the reviews look good and it goes way beyond an intro.

Thanks Tony! I seen it was in last Jan. But I sent an Email to find out if & when their scheduling
for any new classes would be. PS: Dragging my son in on this, Right up his alley Electronics computers & wiring LOL!

Mike, I still run the stock single point distributor in my other galaxie.

I keep talking about upgrading........then I see the cost and go..."it runs okay the way it is" LOL!!!
All the aftermarket distributors are too tall to fit under the snout. I've seen a fancy smancy offset distributor for an FE, but it was like $900!! Yikes. You can't buy points/condensors worth a damn anymore either. This last set really give up the ghost about 5K rpm. The condensor died at 100 miles. I found a rusty one in the back of my toolbox and it seems to be surviving. Having to unbolt the blower to change points is not a high point of my day.

Larry, have you ever considered a PerTronix?

Ya, Chuck. Have also heard horror stories of how short lived they can be. Not sure. With having to rotate the blower out to even get the cap off, I am real hesitant about what I am putting in it. I've thought of putting a crab cap on it, but have had bad luck with cap failures(cracks) and decided against that too. Thus, the ol single points live on LOL!!

I got 13 yrs out of the first set of points and it would hit the rev limiter without issue(6K chip). The new points just don't want to get past 5K without breaking up.

I have also heard about Ignitor problems, but I ran an Ignitor 1 for 2 years, then an I3 for about 5 years with no problems. Only reason I went with the I3 was for the built in rev limiter.

Ya, it's luck of the draw. Not that the car gets that much mileage but want something reliable. I like my junk to get home under its own power.
I've heard if you run the ignitor on ignition voltage(9v) it doesn't last? I wonder if that has any merit?
