The engine in the Pronello Ford is a small-block Windsor Ford with Weber carburetors . . .
. . . which many, including Carroll Shelby, used in Cobras for road racing. The less-seen Ford road-racing induction system was their own Autolite inline four-barrel mounted on a cross-ram manifold.

This set-up was made for Cleveland heads, so they wouldn't fit on engines with Windsor heads.
