Check your Ford dealer for the motorcraft kit, If you send me the part number of the carb, I will be happy to look up a carb kit for you.
On a scale of 1-10 with motorcraft being an 8-10 (depending on the kit) I would rate the Borg warners as 7-8 and the walkers as 5-7. I use the borg warners in a pinch.
As far as years, look for 1970 250 six powered cars (like maybe a maverick or comet.)
E-mail me directly with that carb number and for some more info,
