So I’ve kind of wondered who make a good distributor that will last season to season, pass after pass without needing a full tear down. Also wondering if those same distributors are accurate for racing or better off as street car dizzy. Whould like to hear what Mopar members have gone through with their big/small block distributors.

Crank trigger with a gutted lean burn distributor (no advance) to spin the rotor in the cap.

I've used more than one stock OEM magnetic pickup Mopar aluminum recurved (I shorten up the mechanical advance so it idles between 14 to 18 BTDC idling and has 34 to 36 degrees total advance: up:) in my race motors with good success using MSD 7 series race ECU with the proper coils

I've never had any issues w/ MSD pro billet distributors.

Any gutted cheap distributor with a crank trigger. Mine uses a 440 source. Going on 11 years 850+ passes. Never an issue. Cost wise isn't much different.

Doug...How do you ID the 440 source distributor? I have an aluminum one here but I can't find any markings on it. Sorry for the hi-jack!

I pull apart stock OEM distributors and thoroughly clean and lube the weight pivots and mechanism.

I put in Mr. Gasket #925B lightweight springs (mainly to aid in starting as full advance is all in at low rpm), set the reluctor wheel gap and put on a new Hillman nylon collar (available at Lowes). You can always lock out the mechanical advance mechanism if so desired.

We couple these with an MSD 6AL box and also add timing control (retard only).

This has been simple, super reliable and has given zero issues over the last 7 years with lots of street driving and dragstrip passes (read: abuse!).

I originally set this up with the thought process that if I did a drag and drive event I could easily get parts at any corner auto parts store. Unfortunately, it's getting harder and harder to get OEM electronic pickups, caps and rotors as time goes on. Best to have a stash of duplicates.

Same here. Stock mag pickup distributor, the Mr. Gasket spring kit, a 6AL and a 2 step retard box that activates for either start retard or when triggered by an external source. I use my NOS mini progressive to trigger the timing retard, and it pulls out 9* when the WOT switch activates. Unless the bushings or collar are worn, there isn't much to actually fail inside them.

Same here

Nor Me, other than the annoying ozone corrosion, I clear lacquered it last time and it's held up OK. I also use a crank trigger. I don't gut the dizzy. In the past I've had to revert to using the trigger in the dizzy when the crank sensor has failed, simply a case of swapping the lead

Which part number MSD BB Mopar distributors had the interior corrosion problems that MSD had to fix?

I use an MSD Pro Billet with the advance permanently locked out. Works fine - only downside is that it might rub your valve covers a little at that corner (440).

I too have a MSD Pro-billet and it's been great for about 23 years now

I have 2. MSD part # 8456. Red caps. Both had the same rust issue on the reluctor wheel and pickup, they still functioned OK. The newest one was bought in 2014, oldest in 2011. I now use the black caps on them, they use brass (or stainless) high tension posts instead of aluminium. HTH's

I had a MSD for a while, but they're big, annoyingly big, have to remove the cap to take the rocker covers off big. I recently bought a Summit pro billet distributor & its a good piece. Cap doesn't get in the way of the rocker covers & it uses the Chrysler style trigger. Comparing the prices of all the distributors on the market, I feel these are good value for money.

The Summit ProBillet is the same as the one that Fire Core used to sell - it will self destruct sooner or later! I have had three of them - all did the same thing - pure Junk

How do they self destruct? The Mechanix of it is the same as a std mopar unit & they last forever, im sure Noah had one on his Ark.

I have tried the MSD Billet distributor on two different occasions in my small blocks , both suffered from the corrosion issue . I went back to a stock type distributor and its been fine. I also use a MSD coil and 7AL2 both have had zero problems

I've been running MSD distributors for years with no issues.

If it was the reluctor this will fix it.

Since I’m bad with my hands and rode the little yellow school bus til college, I won’t be working on a distributor myself.

There used to be about 1/2 dozen distributors used since the 1990’s, but looks like MSD is the more popular, dependable unit. It’s the big dollar, but worth it if it work as intended (or better). If the relict or seems to corroded a lot, are this in areas with lots of snow, rain and salt in the winter seasons?
