quite probably... although remember that the XD and XE 351's (which were both rated at 200hp and had 9:1 compression) had 4bbl carbs and 4bbl 2V intake manifolds, as opposed to an early 70's 2v 351 which will make around 230hp with a 600 4bbl holley and the 4bbl 2v intake used on the XD/XE.


Which would make me suspect that the XC 351 with 2bbl intake and carb would be a fairly pitiful performer, although I would also expect Ford not to have net this slip to the public in their marketing.
