MSD Ready to Run

Went through an issue with my Runner where it would run then stall, run ok , then run like crap. Took the dist cap off and it was all corroded from some MSD issue with lack of ventilation. Changed cap, wires rotor no difference. Did all the electrical tests, changed coil, voltage regulator, even rebuilt the 6 pack carbs still the same. Finally pulled the distributor a MSD ready to run. Figured i would swap out the module but MSD doesn't list a replacement so i called. I got some stiff who read me a part # that cost $150. When I googled it was for a Ford so i called back to confirm. This time i got a decent person who told me they were really hard to change as they had to be sodered in and that MSD has a repair program where you send the entire distributor to them and they diagnose and repair for no more than $140. Sent it to them and they called 2 weeks later saying the module and vacuum advance tested bad so they replaced both for $100. I bought the unit new 25 years ago so this seems pretty fair. A new one today with inflation is $600 which im not sure can be justified.

Put the distributor back in and car runs like a top. Just thought i would share in case someone on the board has a similar issue.

I would get a Mancini Racing ready to run at 169.00 before a MSD.

who manufactures those ?

Not sure. They sure seem identical to MSD.

They look like the Pro Comp and several other Chinese offerings.

i kind of figured chinesium was in the mix............
when ain't it used in electronics these days ?

Wonder where MSD dizzys are made.

I wonder if E Berg. Hy-Rev and distibuters are still good.
They used to be.
Funny thing was ij restored a distributed I got in 1978-79 and ran for many year's in different small block. I just last week went threw it was going to post about it.
Was in the 1972 340 rally challenger I was given as had a blown 727 slipped bad. Si tget gave the car away. Then found the 340 block was cracked.

I bought a replacement trigger for the regular msd distributor. Then installed it in the ready to run and run a 6al2. Worked fine until I pulled it.

Due to experiences with my customers cars over the years I avoid pro comp at all cost. I believe their hard parts ore OK but the electrical stuff is total CR-P. If a car comes in with a pro comp HEI, The pickup coil, module and coil all get swapped out. Every time I have not done so I get a phone call shortly after the customer leaves

Also wanted mention that part of my career having been in electronics some which was both Final test and Military QA for Intel an unknown fact to most is that electrical components are tested to different criteria. During these tests there a different classifications assigned depending on a a components response to these tests.
They are sorted into categories such as a Bin1, Bin 2, 3, 4 or 5. bin 5's are rejects.
Bin 1's are considered a premium part and price d accordingly. Bin 2's a bit less, 3's less yet, 4's are the bottom of the barrel and are sold to places like Fry's electronics or other businesses more concerned with cost than performance or reliability.

Some companies will specify their own test criteria such as IBM, Apple, etc. as well as the Military. And OF course are much more expensive than Commercial grade Bin1's.
So when one looks at any electrical device (and likely other things as well) what appears to be physically identical MAY BE, because it is. It was made at the same time, on the same line, by the same workers, equipment etc. But performance and reliability wise tested poorly so it became a Pro comp part instead of an MSD, or other premium replacement item.
The problem is, only those selling and buying the part know what its category or quality is.
These same manufacturing principles apply to just about everything that is mass produced from drill bits to clothing
