Which distributor cap?
Hey guys, I am trying to eliminate my missing problems on my 77 F150 351M, as far as I know it has the factory distributor, and before I try and get the distributor loose(its ceased in the block, and I will probably bust it) I want to try and replace the cap, and rotor and see if that makes a difference......
which one of these cap kits would I need? Or something else better?
MSD Ignition 84085 MSD Ignition Rynite Distributor Cap and Rotor Kits
MSD Ignition 8414 MSD Ford V8 Cap Kit
also, my plug wires are pretty new, if I go with one of these caps do I need different plug wires or anything?

Very true, and brass parts does the trick, too.

I agree with fmc400 on this. That aside, if you have the male prong DSII cap now, your plug wires will work. If it's the DSI female connections then no. Personally, I never buy from Jegs due to the fact they tack on a "handling" charge to each order. Summit beats them everyday.

I don't know if an MSD cap will fit on a stock Ford distributor, because it doesn't matter - we're telling you that there is no reason to do this because this is a commonly stocked item at any parts store, and is very straightforward. If you're under the impression that switching from an OEM distributor cap to an MSD cap will solve a misfiring issue, then you are mistaken. But, it's your truck.

I plan on calling all of the local shops today, and checking what they have........I realize that these MSD caps have no advantage over any other cap I can get locally.......I just dont want a cap with aluminum contacts thats all....

Just letting you guys know, I think I got the issue taken care of..........I bought an Echlin cap and rotor from Napa...........which by the way ended up costing $35.......
This helped the problem a lot, and then today I clamped visegrips on the distributor shaft, and worked it loose with a hammer(It had been soaking in PB Blaster for 3 days)..............I advanced the timing a little bit, and that seemed to pretty much completely eliminate the backfiring issue I had.......
