Cable TB... How did you hook up the IAC?
soon to start 4.7 to 5.7 hemi swap...need help please
So I am soon to start a 4.7 to 5.7 hemi swap...my 2003 4.7 is close to 200,000 miles so I want to start planning out my swap just in case my engine takes a crap..knock on wood though. So I am looking for knowledge of anyone who has worked with this material before. So first off what year hemi works best and out of what vehicle should I get the 5.7 out of? Secondly will my 03 4.7 tranny fit directly to the 5.7 or will I have to make changes
or get a new tranny? Thirdly what new wiring, wiring harnesses, etc will I have to get? I already know that I will have to fab up a new oil pan and that is no problem. I have probably left out much info so please feel free to bring it up. Thank you everyone for your help.

Ok, but what wiring harness are you using? The stock Ram harness' wouldn't have a plug for the IAC, being DBW... Or am I way off here?Its a Mopar Performance TB and it has a NGC 4.7 style IAC built into it.
I guess there are many ways to skin this cat after all... 4.7 harness can work on the Hemi? Makes life a lot easier... And nevermind a TCM flash - I'd do that and a tranny rebuild by default just to handle all extra power - I have no intention of leaving the Hemi stock, not when I can play with it before dropping it in the truck!I have what I would like to call the quickest 4.7 QC Ram around. My Ram had a 4.7 when it started life and has a 5.7 in its place using the 4.7 PCM, Harness, and SCT custom tuning. At my power level, I would not recomeend it without some form of TCM tuning. Its a transmission murderer in a heavy truck.
I have a late 2002 Durango - NGCI had to swap a few connectors using pigtails I sourced from the 07 5.7 Harness, but I have zero issues making sense of electrical diagrams. Your 02 might not be as easy because it is JTEC rather than NGC.
I've read that Jeep Grand Cherokee SRT8 exhaust manifolds fit the Dak/Dur frame, and are basically headers. $90/set on www.car-part.com
I just noticed that... Pick the other manifold, it pops up with 1987 Mitsubishi Lancers! Ok, call me unsure of price, but I've read on here that they will fit.
