Saw this on a capri site (1981 model):3.3 liter inline-6
The 1 barrel carbureted 3.3 liter inline 6 was carried over unchanged. There was also a more somewhat potent version of the straight 6 for the Capri RS 3.3 liter. It was fitted with a 2bbl carburetor, and was rated at 97.5 HP @ 4000 RPM, 161 lb-ft @ 1400 RPM.
