    What's special about the '55 "086" coil?

    Is there some specific electrical value, or is it just the bright finished case? Are the current repro "086" coils any better (electrical function) than Delco replacements?

    o86 is no better then any other, it's the number 086 and cad plating, but only the 55 corvette used it, not CAR and they made only 700 units plus some for the parts dept.
    C2 parts for my 67 are cheaper then a C1 because I have the only small block vett in the world, all the rest are big blocks or L88"s after all they made a con-zillion of them - right?

      There was just an NOS "086" on eBay...

      That went for $155. Most vendors have a repro "086" for about $160, so I think it went a little nutz.

      As for the other, I knew a couple of guys years ago, one had 68 427/390, the other had 70 350/300. Both cars equally fun to drive, unless you were trying to impress someone with the torque in the 427, but you can't drive around with the pedal on the floor all the time, either, so big deal. THEY'RE BOTH CORVETTES. I have driven dozens of Corvettes, and they are all fun to drive.

        Dave,
        I think that the price it sold for was pretty reasonable considering what other less rare coils are selling for! NOS first design 091 coils regularly fetch on the high side of $300, and there were a bunch more of them by comparison.

          OK, so what's the diff??

          Delco went to some trouble to stamp numbers on the cases, but what is the difference? Output voltage? Length & diameter? Cad plate or black paint? I'd be a lot more willing to shell out for a "086" coil if I were getting more than numbers on the can. Bear in mind, I just bought an NOS 55 12V voltage regulator, so it dosn't have to be a BIG reason.

            Dave,
            I am sure that there were some internal differencec like turn ratio or primary resistance, but what it all comes down to is you are paying for the numbers!
            There a many off-the-shelf coils that will work just as well a dramatically lower cost, but they just wouldn't be "Original".

              Dave,
              I can't tell you on this one, but I offer these 1970-72 examples as possibilities for your consideration.
              In this time frame the coil and mounting bracket was delivered to St. Louis as an assembly for the 1970 & 1971 LT1 and 1970-1972 LS5. So in each of those cases, the coil was stamped with the last three numbers of the ASSEMBLY part number. The coils sold for SERVICE did not have the bracket and were stamped with the last three numbers of that part number. Thus the only available original coils with the proper stamping are used units that were at one time installed on engines.
              Having said that, I can't explain why most of the other coils used in that time frame are plentiful, and the SERVICE parts seem to have the same stamped numbers as the PRODUCTION parts.

                Oh great...

                The '55 was equipped with a chrome RFI cap over the end of the coil, no car and no other year 'Vette had such a cap. I can't help wondering if this was just a dressed-up car coil (cad plated case and chrome cap), or if it was higher output voltage or something.

                  Recoil can

                  I think they Cad-plated the coil just for looks because the coil can cover was to take static out of the radio and to add some chrom under the hood.I'm the only one that repro's the shielding and just sold my last complete chrom unit to Dave Ferguson. I no longer will be making them but do have various parts left over. Last chance.

                    Too bad...

                    I have corresponded with Jon Anderson, and even though I have only seen the photos, they look pretty good. The vendors who list the shields will be disappointed. My original shielding is in pretty good shape, but my coil has no raised letters at all! Maybe I can get a CHROME coil...
