As far as money goes? I don't think that would be the best route. Personally if I were going to stick with a 2v, I would either buy a built block, or buy a used explorer engine since they are all aluminum and build it out of the car which would save some money. Rebuild it forged then get a shot of nitrous if you want to save money or a supercharger. Like I said though, I would do the math $ of built long blocks vs rebuild and see which one is more bang for buck.
