Tom - Just to add that the general consensus among the "long-time" Cobra owners (including the Cobra registrar) is that ALL SC's came with 2x4 medium rise engines. This makes sense in that the 2x4 low rise engines for the first street 427 cars came off the Galaxie assembly line, and the Galaxie's switched to medium rise engines (most or many with 2x4) when they became available in production around mid year '65 (before the SC's were outfitted).

There is also talk in the Shelby American staff meeting minutes in 10/65, when just 25 street 427 cars had been delivered, of placing an order for another 125 Nascar engines with a running
change from 8V to 4V carburetors. It talks of ordering the engines with the 8V set-up, but "upon availability of the 4V a decision will be made concerning the change so that we will have a consistent number of cars with the same engine." So their main emphasis early on was dual quads, with the idea at hand to switch to
the single 4V, which is believed to have happened with the 428 (and later MR 427's)......
