Most likely 351. Those are the only ones I know of that Ford Marked this way. 2 indicates a 2Bbl. carb, small ports and valves, 4 is 4Bbl carb. latge ports and valves, same as Boss 351or 351 CJ, the Boss heads would have screw in rocker studs. M is the 351/400 M engine and basically junk. IMNSHO. |
