I have seen some early '54 pre-production TBird brochures that show the 256 engine but the brochuress dated later in '54 show the 'new' 198 hp (292) engine in the images.

Even the earliest production '55 TBirds had the 292...
"For 1955, the first 1000 Dearborn-built Ford VINs - 100001 through 101000 - were reserved for the new Thunderbird. All of these cars had the same 292 cubic-inch V-8 engine (P) . . . "

The one I have is slightly later than this earliest group, scheduled build date Nov. 9th of '54. I suspect one of the previous owners may have worn out / used up the original 292 engine.
Or...
Back-in-the-day the car was in a bad enough wreck to have the frame replaced. Maybe the original engine & transmission were borrowed for another project at the time.
The '54 Merc 256 EBY engine in the car had a '57 tach drive distributor, '57 ECZ-B intake and an Autolite carb from an FE 390 when I got it. It didn't run well at all. Maybe a vacuum leak from the mis-matched intake manifold?

40 Deluxe yes it's odd they didn't list the 1:1 high gear. I missed that, thanks.
I've seen the same transmission specs on at least one other website.
Maybe they're just copying the info from each other???
