Title: MSD 8595
Post by: Skeeter65 on March 11, 2021, 03:55:38 PM
What is an MSD 8595 and MSD wires worth and is it worth using over a factory FE distibutor with points or a Pertronix conversion?
I ask this because I just saw one listed for $400 for the Distributor and Wires. Seller says it's only got 6 hours on it. I believe it may have been in a marine application based on the user's profession and the 6 Hours reference.

For 75 bucks you can get a new Ford Duraspark distributor.  It has the same magnetic pickup as the MSD.  You can run it through an aftermarket box, like a 6AL or whatever, or use the Ford factory box.  The downside is that it still has the Ford advance mechanism, meaning you have to take the top of the distributor apart to alter the centrifugal advance curve and limit.  The MSD uses the GM configuration, so once you remove the rotor, you have access to the advance mechanism.

I spent a lot of money on an MSD 8595 that ran for a total of 20 minutes over several months, never running more than 12 minutes, and I sent it back to MSD who gave me the MOST insane feedback I've ever heard. First it was bad, then they couldn't repair it because the shaft had been drilled for a gear, then then they couldn't replace the drive shaft because they didn't have any (in the entire world!), then they couldn't replace it with a new one because they didn't have any new ones, and finally they sent it back saying it was fine.

It ran for 12 minutes then failed the same way. I never even got my money back. Worked out to about $1,800 an hour running time.

Save your money, buy the Ford piece.

I have the MSD and have about 1300-1500 street miles 80 1/8 mile passes and 80 1/4 mile passes and Im on my second pickup. The last time I drove it before I put it away for the winter I had an extended cranking that I didnt like so I will be getting another one for backup.

Stangman, I can send you the FN marketplace listing if you are interested in buying it. Let me know.

Where’s a good place to buy a new Ford unit? Is there a part number?

I got mine from Faron Rhoads - totalperfentofpa@aol.com - I understand he buys Chinese made knock-offs and rebuilds them (and recurves them) before he ships. Mine has worked a treat, and the MSD is long gone at several times the cost.

Faron is well known in FE circles.

i think a good tight connection and good wiring is key to a long life on these msd boxes.

The Cardone new one.  Sixty six bucks ain't bad for a magnetic pickup distributor brand new with a cap.  You can also look at the later ones like for a '76 truck with the larger cap.  The body is the same, more or less, but with that big cap.

Jim (rockhouse66 on here and other forums) also builds/recurves distributors.   He could probably supply you with a new Duraspark.

For a regular street or street/strip build, a set up Duraspark will work perfect.  I run all MSD and MSD pickups in a modified Duraspark.  Haven't had any issues.  Note - it's quite possible to have the same issues with a stock replacement pickup coil in a Duraspark as it my be to have with an MSD.  Everything is made elsewhere and the quality is just not there.  MSD was really good before it became part of Holley.  Now, I hear more and more things that are "unsettling".

Probably the best option. Just a side note; if it has the cheap cap with aluminum conductors, ditch the cap and get one with brass conductors. Those aluminum ones are junk.

I looked at all the options for a box after having 4 MSD boxs go bad on me and replacing 5 coils in my friends 66 Mustang.
In the early 90's [91 or 92] I bought a Taylor box and it still works.
I went on Summit and found the Taylor-Vertex part number 401001 and ordered it.
Build in rev limiter,will flash a led for any errors,not for a ballast resistor.
Made in the USA and I hope it last's as long as my old one.

I think the older MSD stuff was better quality. I switched my Fairmont from an Accel dual point with a Super Coil over 30 years ago, to a recurved junkyard Duraspark distributor from a 76 F250, and a MSD 6T ignition box. This was before the MSD 6AL was available, the 6T has a plug for use with an external MSD "Soft Touch" rev limiter, which I use with a 2 step for controlling the starting line RPM at WOT before I dumped the clutch. Over 3 decades later, that same 6T box is working fine. By comparison, on my 85 Mustang Stock Eliminator car, I used the newer MSD 6AL, which has a built in rev limiter. In the 14 years that i raced that Mustang, I had 2 6AL boxes fail on me. Maybe just bad luck, but that old 6T has been bulletproof.

All of my MSD stuff is older than shit (mid 90's and older) and and has been trouble free,but I always ran the vibration mounts,I don't know if that has anything to do with it,but has worked for me.Another thing is I always used soldered connections none of the crappy crimp on connectors.
