The May 1971/1972 Q-code Version (351-Cobra Jet, 266 HP) was a low-compression 4V variant employing a cast-iron intake manifold (with telltale spread-bore carburetor flange), special camshaft, hydraulic lifters, dual-point distributor, 4-bolt main caps. A small number of late 1971 351C-4V engines were actually low-compression 351-CJ engines, and were equipped with an aluminum intake manifold.

The 1973/1974 Q-code Version (351-Cobra-Jet, 246 HP) was essentially the same as the 1972 351CJ though with two important differences: Camshaft timing was retarded by four degrees; cylinder heads- though still with large 4V ports - were fitted with smaller valves (2.04" Intake / 1.65" Exhaust), same as used in 351C-2V.

*Your Cobra Jet's 4V cylinder head has the number Œ4 cast into the upper corners for you to see exactly which version of the engine your pony is sporting.
