Technical Mallory mag cap ?

Discussion in 'The Hokey Ass Message Board' started by milwscruffy, Aug 5, 2020.

  1. Found this going through old boxes and from the color of it assuming Mallory ? Whats the extra plug wire port about ? Measures 4 1/4" where it index's into the dist / mag. It was in with 392 Hemi stuff. Don't see any numbers except a 1 on the inside of the cap. Appears to be NOS . Thanks for the help 102_1402.JPG 102_1403.JPG
     
  2. I think you have a Du-Coil cap, I don't know much about them.

    I believe they use two coils Du(al) Coil

    I found a complete N.O.S. S.B.C Du-Coil at a swapmeet several years ago cheep, doubled my money in about 45 mins my friends said I didn't ask nearly enough. I was happy, the guy who bought was a friend and needed it.

  3. Thanks, did a quick search and came up with nothing. I can see it now, so rare no one needs one !:D
     
  4. They were hot a short time ago, they may still be. I stepped away form the hot rod scene a couple years and got heavily involved in vintage oval track racing. So I am a little out of the loop.

    @Moriarity could give better insight on how the work and if the are still in demand.

    If you are looking to sell it PM me. I have two DuCoil distributors in service and I’d like to have a spare cap and rotors

    yup W&H dual coil... caps and rotors are pretty tough to find in good condition. you see a fair amount of them with plug wire towers broke off. I think they are made of something brittle

  7. So what did W&H stand for ? First I've heard of this brand.

    I never really looked into the history of W+H, no idea who W and H were. I had one in a car I built back in the '60s and it worked well. During the update of my roadster I'm installing a 324 Olds and hydro similar to the combo I had back then and I found the same distributor.
    I believe they were eventually bought out my Mr Gasket Corp.
     
  9. Harman & Collins were involved Du-Coils at some point correct?
