I just purchased a 86 4x4 ranger with a 2.8L that had been installed to replace the original 2.9L and I would like to switch it back to the 2.9L and restore it to original. Can anyone let me know if this is doable and if so should I be prepared to redo wiring and computer modules. Any info would be greatly appreciated. Thanks
