Might check Motors Manuals at the library or oldcarmanuals on line. The 7043014 carb (thats the number on the little tag, right?) looks like 1973 vintage, probably car since I dont see it in the truck sheets. So my guess is a 1973 car 250cid, you'd have to hunt for the rest.
Both of my "MV" parts carbs have the same jet and rod as above.
