Just to eliminate this procomp crap I bought a few years back I bought an MSD 8361 distributor. The wiring directions only show it going to different types of controllers, can I wire this one directly to the coil or do I need the controller box as well?

That model requires an ignition box. Can you return it and get the MSD 8360? MSD Ignition 8360 - MSD Pro-Billet Ready-To-Run Distributors - Overview - SummitRacing.com

yeah MSD gave me the wrong number, I reordered the right one, thanks

I think I read in your posts that you purchased the Blaster High Vibration MSD-8222. Just want to make sure you have a good coil for your new distributor. When installing your new distributor make sure it is grounded good and the battery lead is disconnected. Don't want you to burn up the module.

Thanks for the info, will the MSD-8222 be okay with the MSD distributor I ordered?

[cdminter59]

Yes, The MSD-8222 is all you will need. The instructions to wire it up should be in the box.

Hey everyone, with all youre help I think its fixed, I replaced the coil and distributor with MSD parts and that fixed it so far...thanks for everyones help and hopefully this forum thread will help someone with the same issue

Well, I hate to rub it in because I know everyone wants to save money anyway that is possible. When installing new parts especially high performance parts buy the known brands that work. If something is $100 cheaper for the same part warning signs should go off in your head! Buy the correct part once, use a coupon or another store that has a sale. I have saved alot of money buying name brand parts using coupons from the internet from stores such as StreetsideAuto.com, SummitRacing.com (No coupons lately). It pays to compare prices. Glad everything has worked out for you!

Actually the Root Cause of your problem could have been an impedance mismatch between the Procomp electronics in the distributor and the MSD coil. I know that Procomp advertises that this works with anybodys anything coils but that's likely to be more advertising than engineering. There is a good chance that the Procomp module would work happily with a Procomp coil. Or that putting the MSD module into the Procomp distributor would have solved the problem.

One of my big issues with the hot rod industry is the lack of genuine technical data 70% more power than brand X's coil is not really useful information. Our ignition module is impedance matched to a 50 ohm coil is useful engineering data.

Back in the good old days of modular stereo systems if you plugged 16 ohm speakers into a 8 ohm amplifer you could count on buying new speakers or amp, or both in the not to distant future. You've got a same/simular situation here between distributor module and coil another exists in the drivers for fuel injectors between high and low impedance injectors get this wrong and you will find youself buying a new computer or new injectors or both.

So whether this is a problem of Procomp being of less quality or whether it was caused by using their distributor module against an MSD coil remains an open question in my mind, a spare time experiment someday perhaps.

I know this is a procomp being cheap problem because I tried 2 MSD coils, and 2 procomp coils, both procomp coils worked for a few months then gave out, also had 3 vacuum advance canisters go out and my truck never backfires and 1 distributor go out for bearing noise. From what ive gotten from procomp its all junk apparently.
