How many CURRENT owners of real '74 360 Duster 4 speed cars on here?
Good stuff, but I don't think it narrows it down enough. There are 3 potential casting numbers for a 74 A-Body, but maybe one for a 318, one for a 360 in an A-Body and one for a 360 in an E/B-Body? Did the 318 and 360 have the same manifold and the numbers are one each for the body style?
