Factory dual point I know the 12127 id's a distributor but how to decode the rest of the numbers? it has an H like most on the left side of the tag, under that the numbers 542. To the right side of tag is FEC and below the 12127 B
Anyone know what this decodes from? Mummerts site starts 57 & up.

8 Cylinder 272 engine, FEC 12127-B application...
'55 A (passenger car),
182 H.P. Special w/ F/M, with 4 barrel carburetor

Distributor Catalog Symbol (for component parts list) - 12
Ford part number - B5A 12127-F

Your distributor superseded Ford part number FEC 12127-A which had the distributor stamping FEC 12127-A
Part number FEC 12127-A was replaced by Ford part number B5A 12127-F
At first blush, they changed one distributor ignition advance spring with the distributor you've got.  The FEC 12127-A unit had two identical advance springs

Interesting...
The '49-'59 Text Catalog has no listing for a '55 H.P. Special 272 engine equipped with a standard or standard w/ overdrive transmission

Hope this helps.

Thanks! I wouldnt have thought they made a dual point for the 182 HP though, unless somebody changed the breaker plate. The plate has Dyna-Flyte model 218-D, guess it was a period aftermarket conversion plate.

That was an after market dual point conversion plate, they were a common performance upgrade back in the day..

Rusty on this, Billy.  Dyna-Flyte was a maker of aftermarket dual point conversion kits back in the day.  I found several for various years and makes '50s and before on eBay.  I vaguely recall that the company supplied some of the 'big three' manufacturers with some ignition related items, I think.  

Here's a current eBay listing for what is likely in your '55 distributor if you click the link below.

As you likely know, Ford used a dual point distributor plate in the '57 F code distributors along with a 10 degree distributor cam instead of the 13 degree unit that they used in all of the C, D, and E code units in '57.

The no std or std -OD transmission availability with the 1955 Power Pack engine is apparently correct.  It's suggested that Ford thought their T-86 trans was marginal for it.. Unfortunately, their nearest competitor apparently did offer their Power Pack with a stick transmission..
