In 1960 Jaguar upgraded their XK engine to have a displacement of 3781 cc. This was achieved by increasing the bore and offered 220 bhp over the standard 190 bhp 3.4.
Like the previous model, an optional Special Equipment Model was available which used the B-Type cylinder head and twin SU HD6 carburetors. Other refinements included wire wheels, dual exhuast, windscreen washers. Above and beyond the SE model was the S-Type which used a straight-port cylinder head and three HD8 SU carburetors for 265 bhp @ 5500 rpm.
