Has any body seen or heard of anyone having the 4.7 V-8 that is in the Durango/Dakota put in a JK. I had an 06 Durango with this engine and it had plenty of power/torque and gas mileage was the same as I am getting with my 07 wrangler.Some one with more mechanical knowledge than I have might be able to tell me if this conversion is posible,I believe it is, especially if 6.1 hemis are being put in the JK.
