Hi all.

I play with my thought to buy a new distributor. But I donīt know what is the better choice. After a long search I have a tighter selection between MSD 8572 and Mallory Magnetic Breakerless 5764501 distributor.

http://www.summitracing.com/parts/MAA-5764501

Both are equipped with mechanical tach drive and vacuum advance. MSD requires a ignition box, Mallory needed it not.

Has anyone good or bad experience with this distributor typ?
Please let me know your recommendation?

One more question.
Does anyone know whether the MSD Distributor PN#8572 fits under the early 70th C3 ignition shield? -This could be a decision to buy. I would like an original optic.

Thanks in advance for your reply!

Regards
Andreas

i always liked Mallory but both are quality units.either one should fit your car

A few months ago I agonized over this..

Although the Mallory is a stand alone and a bit cheaper, I went with the MSD. My 2 pieces of motivation were:

1. MSD ignition box eliminates any problems associated with factory wires/voltage going to coil

2. Replacement ignition module for Mallory is still like $80....granted thats cheaper than a new MSD box, but I have used MSD stuff for 15 or so years and have faith in the brand

why not run a well-built/rebuilt ACDelco tach drive distributor like OE 1970 C3?

Points work fine for most but, ... perhaps replace points with Crane XR-i , lectric limited Breakerless SE or similar. FYI, B-SE is a true one-wire piece and only a few can tell by looking that it's not OE points.

After all, above are much less $ than msd or mallory but make plenty of fire for all but true racers w/ huge compression ratio.

I had also weighed in the idea of rebuilding the original tach drive...

The price of rebuilding the stocker, or buying a rebuilt unit, with all of the tach drive parts etc is still not cheap, and you are still stuck with the crappy factory advance curve.

MSD distributor has tremendous adjustability for your preferred advance curve.

Good points to consider. I guess I'm 50-50: use a Mallory tach-drive distributor with the MSD 6A box. The combo has worked well for many years of trouble free combustion sparking.

Thank you all for your answers, I think I have made my choice. Iīll go with MSD.

I still have one question. Can I further use my existing ignition cables?

I beleive you can get a female cap for stock style wires.

Nitrous 74

I'm about to make the same decision, thinking of going MSD. Anyone know a part number for the female cap? I just installed new plug wires.

MSD all of the way if buying new......
It is MUCH easier to adjust your advance curve on the MSD.
New mag trigger is only $30.
Two caps are available for the MSD....post and socket....

I hope the msd female cap fits the msd dist better than a stock delco dist that it is supposed to fit. Very bad fit on the delco dist, at least the one I got.

I did this too (Unilite) but wanted vac advance. Tried the Mallory magnetic p/u distributor but it never sparked. Bought a Davis HEI and am very happy with it. One wire, vac advance, and works great.

Just an FYI MSD now own Mallory and they had discontinued production of Mallory brand ignition as of 3/31/2015. They also own Accel, and they say they are honoring warranty and making spare parts but I can tell you many of their parts do not interchange and there is no alternates for some Mallory items including coils.

If I were you I would stay with MSD.

Its too bad MSD doesn't make a "ready to run" distributor w/ a tach drive, best of both worlds!

wilcar

Some of the lower priced msd distributors like the streetfire are made in china.

Jebbysan

I often wondered that too....but after having the MSD tach drive with 6AL....on my 66'.....I would never run anything else.....

Started EVERYTIME and the curve was wonderful......pulled like a train.
Crisp and clean....

When I had my '69 L46, I wanted to refresh the stock distributor at the same time as the OEM q-jet. Sent both to Lars. At the time, Lars was blueprinting stock (points-style) distributors.

He did a great job on both. I continued to run points as the L46 was driven under 5k miles per year (AC Delco are usually good for 1-2 years in these conditions).

You could always have the stock dizzy blueprinted and then add one of the pertronix, mallory or other breakerless ignitions added into it.

Just a thought.
