not that it matters much, I have a stock, all original C code, 289, 2V, build date Jan3 1968, San Jose; had 302 air cleaner decal but eventually replaced valve cover gaskets and voila: stamped in head is 289 just like photo above. I think these were leftover motors from 1967 cougars, 'Stangs, as 302 came out in '68 but usually reserved for more luxurious XR7 with AT, PS, AC, PWER brakes and windows. Mine is a 3 speed floor like a Mustang. For years it perplexed me; its stamped in the head. The Vin code tag next to the dipstick was actually accurate as was the VIN # assignment. The decal was false. Again no big deal, madras blue color (only '68) and non-issue, original period Cragers gets many a thumbs ups while driving. Snagged Driver Dream prize @ a Hemmings cruise-in.
