Help me pick a distributor!

I've got Stealth heads on 383, no head clearance problems. My large aluminum valve covers needed to be dimpled a little, but I do believe he has changed the cap to resolve that issue.

Thanks, mine has Stealths on the 400.
 
Thanks all, I decided to go with the progression unit. Will report back once I have some time to tinker with it. :thumbsup:
 
It's been a very busy spring, so just now getting into the garage to put in some work.

Install was very easy. Out with the old, in with the new. I have 440 Source heads and the distributor is very close, but there's no interference.

Getting the app running is also simple, just enter your code and it syncs with the distributor.

Out of the box without any config it is at a static 10 deg of advance, so just position distributor until you see 10 deg of timing and lock it down.

After that, use the configuration wizard and fill in some basic info. There are some limits in the app, so I couldn't just go straight to 40 deg of idle timing. Here's what I used initially:

It then generates a base table, mine looked like this:

RPM is across the bottom, vacuum in kPa is on the y axis.

With a 900 RPM idle, timing was 24 degrees. I verified with the timing light and looked close but not quite. I did reposition the distributor to back it down a degree or 2. It was bouncing around a bit when it only had 10 deg in it.

The only changes I've made so far is to set 35 degrees of idle timing:

So far it idles very nicely. Rain today, but I'll get it out for a drive tomorrow and do some more tinkering.

I'm very pleased so far. I did not opt for the launch or NOS control, but the guy said if I wanted to add it later I would just need to send it back to be unlocked for the $200 differential.

I'll update as I get some miles down :thumbsup:
 
Surprised they don't have a MAP sensor option so you could completely ditch the old vacuum unit for good.

Nice report. I'm glad to see forum members posting good, thorough information about the Progression system.
My dedication, calling my "approval" of the Progression system "dedication" seems an appropriately strong a term, happened when I discovered their product was the materialization of my dream, my concept of the ultimate ignition system for carbureted engines. I had encountered a "home crafted" mish-mash of a tablet computer, several electronic components, and a distributor that a guy had put together at an out of state Mopar meet for his own car, and it had similar functionality but was unreliable and unwieldy.
Anyway, once I finally got my Progression Ignition my 440 6bbl threw a rod and then soul-shredding grief and tragedy struck in the form of a vindictive wife who struck at a time when I didn't have the financial wherewithal to win a fight to keep my Roadrunner and keep a roof over my head, and would have lost the Roadrunner anyway.
So the Progression awaits the glorious day when it finds a home in my long awaited 572 stroker.
Until then I have to live my Progression dreams vicariously through those of you who are using theirs.
 
Here's my "map" for my Progression Distributor. It "ran" good until I broke a pushrod Oct '22. Hoping to have back on the road this summer.

I am also in the Progression Ignition camp. On my old motorhome 440 with iron heads I have found the sweet spot to be 20 degrees of idle timing with 38 all in @ 3000rpm with an additional 10 degrees of vacuum advance for 48 degrees. It runs very happy here.

@funknut I noticed in your last post that you said you "repositioned the distributor to back it down a degree or 2", and I am not sure of the consequences of this.

It's meant to be manually set at 10 degrees, very steady @ around 900rpm on the balancer (assuming yours is accurate) and then ALL further adjustments are done via the app. You do not adjust the physical distributor afterwards.

Maybe I read what you said wrong, but if not, I would set it back up again properly.

No, you're correct. At 900 RPM and 10 degrees of timing it does not idle very smoothly, so I was a bit off when I aimed for 10 degrees. Once I got it fully configured and running with more timing it's much smoother and I was able to match what my timing light showed to what the distributor was showing in the app.

Glad you got it sorted in the end. :thumbsup:
 
Does the Progression distributer clear a 4 or 6 BBL air cleaner base? I know a lot of distributors don't. Thx

I think it's partially due to your enthusiasm of this distributor that caused me to reevaluate my ignition system. Myself & my 440 have been very happy with the purchase, as others have stated. I now do a little Progression preaching myself at car meets when asked about my engine.

Very sorry about the situation with your RR. You will find a new home for the Progression. Can't keep a mopar guy down. :drinks:
 
I've had a couple months and now with some warm weather I thought I'd report back.

So far, it's been flawless, but I probably have under 300 miles on it so far. The additional idle advance has been great at keeping engine temps down. No more stress in stop-and-go traffic watching the temp needle climb.

The app is really intuitive, but once you get the curve set you almost never need it again. I keep it open for RPM until I get my tach sorted. It quit working moving from the MSD to Progression.

It has an option in the app to lock the distributor. I haven't needed it yet, but might be good for some peace of mind.

Thumbs up from me!

Good report. I'm not surprised.
It's such a great concept, and apparently well executed.

The old dash ignition switches in these cars is so easy to start w a thin pocket knife. Anything I'm at a large shopping center, casino, etc.... I use my ignition lock.

The Progression Ignition lockout is SO easy to use, why even risk ONE chance of a minute away from your TREASURE to find it gone because you didn't use the security tool available?
That would be worse than Peter Best, the Beatles drummer who quit the band right before they became a phenomenon!
Talk about perpetually kicking yourself in the ***, several times a day, and overnight too..
