I have a 79 bronco with a 460/C6, other than the fact that it's carb'd it runs great. Sometimes I even get 11 mpg! The downsides are it stalls a lot off road and there is some serious weight in the front end. How would a 351W/NP435 work out? My guess is I would lose 150lbs or so and pick up a couple mpg's, plus fitting an aftermarket EFI system would be easier... True? Not True? Total waste of $$$?
