Hey m&m when the refer to cam arangement it is the number of cams above the cylinder bank therefore a DOHC cobra would have 4 cams( a v8 has 2 banks) but also be DOHC and a GT which is SOHC would have 2 cams one for the left and one for the right bank Got it???????????????? You usually dont hear of a cobra being reffered to as quadruple overhead cam.
