Don't think so. It does look like a "welded" type aluminum manifold, but I think it is a 1 bbl carb. Look at the throttle shaft (can't see the whole carb). The shaft goes from front to back. The 2 bbl carb has the shaft running cross ways.
If it is a 1bbl, he can use the early carb and stock (non cut) linkage, or stay with the carb on there and convert to the later cable style pedal and cable. He can leave the trans kickdown as it is, if he changes to the correct rod linkage. If changing to the cable linkage the kickdown will have to be changed.
