Need help with an engine swap please.
I have an 07 Grand Cherokee with the flex fuel 4.7. Can I swap the 4.7 with a
5.7 or a 6.1 with no modification? The engine I currently have keeps acting up
and I really don't want to keep dumping money into it. Or should I just get
another 4.7? This is in a Grand Cherokee Laredo with the 4X4 2 (not really sure
what 4X4 2 is.)..
