Im using a dual quad Blue Thunder manifold on my 522cid. with the race track aircleaner. Im having a problem finding a distributor thats short enough to clear the aircleaner enough so there room between wires and aircleaner without worries of arcing on aircleaner. I have a MSD small base pro-billet with 6AL, it is 9" tall, Im looking for something shorter other than stock if possible. Any suggestions as to what distibutor may work? I can't use carb spacers as there's no more room under the hood. I want to use my aircleaner no matter what, it is a chromed Cobra aircleaner and have some $$$'s into it and im using it! I can't believe MSD doesn't offer a lower profile cap for my dist. that sucks! All I need is another 1/4-1/2" shorter and the pro-billet would work fine. Options please?

Mallory marine flat cap unit should do the trick Gary.  ------------------

I am having the same problem with my 71 Mach. I have all the stuff for the ram air but every since I replaced the Unilite with this MSD distributor, the factory cleaner will not clear the cap. Alex, are you saying the Mallory cap will fit on the MSD distributor?

No guys, use an entire Mallory flat cap Marine distributor. The kind that the terminals come out of the side of the cap instead of the top. I'll check and see if MSD offers a similar set up in conversion form. ------------------

How about just using a points style ditributor cap. You can remove the adapter and the large diameter male post cap. That's what the early for duraspark set-ups used until they switched over to the larger caps. That's what I run with my MSD ignition and it works fine. Just an idea, if you haven't tried it yet.

The small base MSD didtributor already uses that configuration Mike. ------------------

Mine had the adapter and the larger cap, but I got it several years back. I switched to the smaller cap because it looks more factory that way on my 70. I love the sleeper look. I didn't know which cap he had so I figured I'd mention it just in case.

I had a similar problem with the Accel Billetproof distributor with a Ford tri-power on a small block. The Accel female cap with wires would hit the oval air cleaner, switched to the replacement HEI type cap with retainer and everything clears with room to spare. I had the conversion cap on order at Summitt for over three months, Alex found one for me within a week. signed, sealed, and delivered. Thanks Alex...... Mike

Great responses, thanks. I was looking through the Summit catalog and see Mallory offers a conversion kit changing over a single points 1957-1974 Motorcraft dist. to a Unilite. There's one option as the Motorcraft sits real nice and gives all the room I need. The other option I'll have to call about is the Flat cap marine mallory Alex mentioned. As it stands now I have a 1/2" between the posts on my MSD and aircleaner, after installing the wires I have a 1/4" clearence. Bit to close huh? I could sneek the wires up there but would rather not take the chance and have it cause problems down the road. Here is a pic of how close things are on my page, the aircleaner hangs over the dist. even with the coil post on the cap. Http://hometown.aol.com/garyslight/myhomepage/index.html

Another question if anyone here knows, why do all the aftermarket companies make their distributors so darn tall???? If it's for clearencing something, clearencing for what??? If you ask me, They should make them the same specs. as a stock distributor and just improve the internal pieces. Temp. issues should not be the reason to build them as skyscrapers!! The designers are not taking in account for all variables thats for sure.
Another thing, here MSD makes them from solid blocks of alum. and call them billet---wow big deal! then they go and still use bushings instead of roller bearings, whats the sense??  [This message has been edited by Gary (edited 04-13-2001).]

Actually if you have 1/4 inch of clearance you should be fine with a good quality wire set Gary. The air cleaner will move with the distributor when the engine moves. ------------------

2 cents worth:
I have the Mallory marine cap that Alex mentioned on my 302 in my '69 By using the flat cap, it allowed me to keep my straight MonteCarlo bar located between the shock towers without it interferring with the distributor cap/wires... Sure, I I could of used the 'curved' MC bar, but figured the bar wouldn't provide the rigid support between the towers I was wanting from it - so why would I even bother with the 'pre-bent' bar...
