This is actually a pretty popular swap, probably because people like the looks and all of the car, but when the engine needs repaired they find out how expensive it can be. I've seen quite a few of these swaps over the years and they seem to be pretty efficient. Plus you can go to any parts store and pickup parts cheap.

It does seem to devalue the car somewhat as I have seen some of these for sale for cheap money, but that is not the reason people build one in the first place. I bet it handles better too because I would suspect the sbc weighs less.
