Definitely a 34 ford grill and an injected big block but the chopped cab is more than likely not a Ford as all ford coupe utes had the small side window behind the door widow, could be a Willys or a Dodge or a made up bitza made up from a sectioned (cut and shut) sedan, the faint join line on the roof towards the rear of the door sort of gives it away, a good example of a rat rod.
