Found an Autolite 4100 4 bbl 1.08 marked C4GF AF B 4EC. It is listed as original for a 64-1/2/ 65 Mustang 289 AT C5OF-J

It comes complete with instructions & an installation video. Also included a 2001 restoration bill from Pony Carburators in N.Y. There is also a reference to a Hi Po conversion on the $600 bill. (no details?) Question is, would it be suitable for a 57 car c/w 312 auto ? It appears it has never been reinstalled. Price now seems very reasonable. Any info appreciated, thanks.
