Found 2 TI coils under the work bench. Both are embossed coils.
One is a "207" and other is a "263.
What application requires these coils?

Re: TI coils
The '207 was used on most SB cars equipped with TI in the early-mid '60 era. The '263 is a hard critter to find as it was targeted at high horsie BB cars with TI in the mid-60 to early '70 era (L88, LS6, Etc.). Both are NICE finds, amigo! -

I agree with Jack on the applications. Also, the GM #1115207 coil was available for MANY years in SERVICE. However, original PRODUCTION versions (as well as most SERVICE versions until the early 1980s) had embossed (raised) lettering on the can. Later SERVICE versions had white silk-screened lettering.
The GM #1115263 is rare not only because it was used primarily for big block with TI applications but also because it was NEVER available in SERVICE. For SERVICE requirements the 1115207 was the only coil available for all applications.
How come the PRODUCTION part number for the big block coils, both standard and TI, are different than the SERVICE coils whereas for small blocks the PRODUCTION and SERVICE coils are the same part number (although, of course, different for standard and TI)? Well, it's "very simple". For small blocks, the coil bracket was installed at the engine plant. The appropriate coil, standard or TI, was installed at St. Louis. The embossed number on the coils is a derivative of the actual part number of the coil "all by itself".
For big blocks, the coil bracket was NOT supplied with the engine assembly; it had to be installed at St. Louis. For some crazy reason, the big block coils were supplied to St. Louis as an assembly with the bracket and, incredibly, the number embossed on the coil was not the part number for the coil; it was the part number for the coil + bracket assembly!
So, if you remove a '263' coil from it's bracket, it's no longer a '263' coil. It's then a '207' coil, except that the numbers on it don't "go away". They stay right there. And, that's why the '207' coil was always the SERVICE coil for big blocks even though you don't find that number on any original, PRODUCTION big block coil. Since coils were NEVER supplied to SERVICE as an assembly of coil + bracket, the '263' coil was never available in SERVICE.In Appreciation of John HinckleyComment
