Aftermarket street/strip car ignition

Who today makes a good ignition system for my car. I think I may retire my old MP ECU and want something that is dependable and will make some RPM's. No crank triggers.

For a race car the standard setup of a MSD billet distributor and a MSD 6 box seems to work for most people. If it is a street/strip kind of deal where you want vacuum advance then the choices are a little tougher.

I guess I should have added that I don't run vacuum advance. It's a recurved distributor and is at full advance around 2500 rpm. Just curious if there was anything out there other than MSD. Just seeing what other options there are.

If you are looking for something other than MSD then that is the question you should ask. You'll get better answers if you ask that question.

why don't you want to run vacuum advance ? race only engine i can understand, but if you do any street miles at all, vacuum advance is your friend.
it will take a little tuning of the advance curve inside the distributor, plus adjusting the can [and possibly changing it for a different unit] through the hose nipple, but it will be well worth it in the end.
see the article by e-booger on the "mopar action" magazine site for the how to.

I used the msd streetfire box with good results.....a little cheaper than the 6-AL, has got a rev limiter too and performed flawlessly.

I wouldn't buy and try to use a MSD 6AL digital, I know to many people who had them fail I've never used the MSD street # 6 series boxes but I know a lot of racers that use them on their bracket cars
I still like and use MSD race ignitions on my race cars, 7AL2, 7C, grid and so on

What’s considered Some RPMs ?

What are you shifting at now ?




I love the Firecore distributor with vacuum advance - Adjustability is awesome and easy , ported vacuum - Use factory distributor cap and decent wires

Older Direct Connection Mopar Chrome ECU or the Older Standard LX101 ECU ignition modules


I considered upgrading to a MSD Streetfire module or Pertronix Digital HP when I was chasing RPM issues until

Coils and Ballast


But on a 500 HP Street car , in all honestly what would I gain ?

Starts awesome , idles awesome , destroys the tires awesome , shift around 5400 RPMs with my cam and valve train



Putting together a great quality Factory Stock Type Performance Mopar Ignition System is a little harder today with all this Chinese junk
I guess in reality that’s the biggest issue

I found all my new old stock ignition components on EBay and swap meets

The Firecore distributor, so far so great on the street

I shift 6300-6500. I'll never buy another Firecore distributor again. Firecore wires are great. These newer ECU boxes are unreliable and I usually get misfires around 5800-6000 rpm. I'm not into buying used electronic devices. You usually are buying someone's trash that should be thrown away. Stock ignition works great but it has its limits. And I figure it's time for me to upgrade.

Anyone familiar with ICE ignition?

FWIW...I ran the old school MSD 6AL box for a LONG time. Still have them on both B bodies we have and I'm putting one on the Demon.
The only reason I went to the 6530 on the cuda was all the extra features it has helps w/ the nitrous.

I had problems years ago w/ the first MSD Digital 6 Plus boxes. They seemed great, until I couldn't get rid of a high RPM misfire. Swapped the old 6AL back in and it was gone.
I think the early digital boxes were plagued w/ issues the newer ones don't have.

Good to know. Thanks Chip. I'm kind of leaning toward the 64253 6AL and get the coil and a pro billet distributor to match. Not sure if this would be a mistake or not. I'm just naturally aspirated with my hemi.

I like the 6421

Either of those should be just fine. The 6530 just has a lot of extra features (needs a laptop to set it up), which really aren't needed for your car IMO, but is nice if you plan on doing something different in the future.
The one you're looking at is just the new digital version of the old school analog 6AL.
