If this is posted elsewhere, my apologies, but I havent seen the question. Does anyone know if the 2008 4.7 will mount into our WJ's? I have seen in WJJEEPS that the Hemi wont swap due to size issues, but the 4.7 should not have that particular issue.
Don't think that it will work. The engine itself should not be the problem, but the PCM of the WJ uses a single wire PCI data bus to communicate with the other components, and the WK uses a double wire CAN bus.
