plk Posted July 21, 2017 Share Posted July 21, 2017 Does anyone recognize this 16 cyl distributor cap? Link to comment Share on other sites More sharing options...
Dave Henderson Posted July 22, 2017 Share Posted July 22, 2017 I can't make out the lettering, tell us what it says please. Is there a maker's logo? Some possibilities; Nash ambassador 8, '33-'41 had dual ignition with an Auto-lite cap, also some fire engines with 8 cyl. Lycoming engines, V16 Cadillac or, Marmon maybe? Or Peerless V16 (1 prototype in '31, not likely) Link to comment Share on other sites More sharing options...
nzcarnerd Posted July 22, 2017 Share Posted July 22, 2017 The lettering at the top (at 12 o'clock) says FIRING ORDER. Now we just need to find a reference with the firing orders of various multi cylinder engines. Link to comment Share on other sites More sharing options...
Dave Henderson Posted July 22, 2017 Share Posted July 22, 2017 (edited) "38-'40 Cadillac V16's firing order was 1-4-9-12-3-16-11-8-15-14-7-6-13-2-5-10, so that eliminates those year Cadillac V16's, but leaves the earlier ohv 16 version to ponder. Wish I could read all of the firing order on the cap, that might also eliminate the dual ignition Nash and fire truck 8's with 2 plugs to a cylinder.

Johan Boltendal Posted July 22, 2017 Share Posted July 22, 2017 To me it is a distributor cap for a Cadillac 452 A B C D and the 36-90 , top outlet , early engines came with a side outlet for the plug cables, firing order is correct for the Cadillac V-16 Link to comment Share on other sites More sharing options...

I've repaired interior cracks on rare caps by (1) Dremel-drilling a shallow hole at each end of the crack to keep it from propagating, (2) applying about 5 single-stroke coats of epoxy fingernail polish, coats one day apart.
