Remove MSD ignition box

Hi,
I have a MSD 6A ignition in my -67 Camaro. It has a 327ci/210HP engine modified with an Edelbrock Performer intake, 4-bbl Rochester QuadraJet, Hooker headers and a 2.5" Magnaflow exhaust system as the only modifications as far as I know.
Have read that a MSD ignition is not needed on an almost standard engine and that it probably is a source for future problems.

Can I remove the MSD box and just run it as a non-point ignition?
Do I have to swap the distributor?
Do I have to buy a electronic ignition kit?
Also, what brand of distributor do I have?

Well, a lot of questions from a newbie...
Have added some pics below of the MSD parts in the car.

Rgds/Mikael

Re: Remove MSD ignition box

Judging by the MSD rotor, I'd say you've got an MSD electronic distributor, so you need the box to control it. I don't see any reason that you'd have issues with the MSD setup on a stock engine- it's not a necessity, but it shouldn't hurt anything. Is it running OK for you?

Re: Remove MSD ignition box

Mikael,
You have an MSD distributor, as seen by the magnetic pick-up and reluctor wheel below the rotor. You do need to run the MSD 6a with this distributor and although it is not required for your engine it certainly won't hurt. It will give you easier starts, cleaner burning of the fuel as long as you maintain the tune-up/carb tuning. I have been running the same distributor and an MSD 6AL for over 15years without trouble.

Have had problems with backfiring but it was the ignition cables. When replaced it runs without problems. I was just thinking of removing the MSD box because I have read that they are famous for causing a lot of trouble.

I will keep on using the MSD box since it is not causing me any problems.

Re: Remove MSD ignition box

Bob and Tony,
Thanks for the information of what distributor I have. Might be good to know at some point.

Re: Remove MSD ignition box

Have MSD run the serial number for you and see how old it is. The older it is, the better it probably is given their recent track record. I've got an old 6A that's been on my supercharged S10 for about ten years that's never had a problem.

Re: Remove MSD ignition box

I have been running and MSD 6A with an HEI with a supercoil and my car recently began starting hard. I am reworking my wiring harness and to clean things up in the engine compartment I decided to remove the MSD and just go with the HEI and supercoil. Now it starts immediately, kind of weird.

Re: Remove MSD ignition box

Depending on the MSD distributor you have you may not need the box. The "ready-to-run" units like the 8360 don't need one but some people use them. I have the 8360 and it looks just like that.

Re: Remove MSD ignition box

Once again I will thank you all for the answers.
Since I am born as curious guy I wonder how I can check what MSD distributor it is?
Do I have to remove it?
I guess I should be able to find a number or something somewhere. Have looked from all angles when the distributor is in the car but have not seen any kind of numbers...

Re: Remove MSD ignition box

It looks like you have MSD model number 8361 distributor. You need an MSD ignition box in order to run that distributor. If you remove your ignition box, the car will not run with that distributor because it does not have its own ignition module in it, only a magnetic pickup which signals the box when to fire. You only have a two wire plug coming out of the distributor,that is what gets connected to the box.Hope this helps.

Re: Remove MSD ignition box

If you are having problems with your wires, make sure you ARE NOT running graphite or solid core. USE ONLY spiral wound wires.
