Selling as whole for parts or if you wanna finish it. 4.0L Engine has been rebuilt, bored 30 over and crank is 10 under. Mild cam and headers. To get the engine running well, I think it could be done with just an O2 sensor or emulator because fuel system is tuneable. It's a paperwork nightmare and I bought it as a young dumb kid who was more ambitious than I could handle. If you have any questions feel free to text (6six1)six3three-4three9seven
