Hemi Swap Complete - 2002 4.7 to 2003 5.7
#61
WhiteRam~ Thank you for serving our Country..I for one appreciate it. The Viet~Nam Vets didn't get the appreciation they deserved when they returned home , so every time I see someone with a Viet~Nam Shirt or hat on , I ask "Did you fight in Nam"? If he says yes , I thank him and shake his hand..I have a lot of respect for those guys..Or anyone who fights in a War , no matter how senseless ..
NOW~ For the question. If you use a 2003 ECM+TCM and wiring harness I don't think you'll have to worry about the front wheel speed sensor. I don't think 03's have 4 wheel ABS..BUT you might have to do the same thing I'm doing to get the cruise to work..4.7's have a vacuum type cruise control that works the throttle cable. Since a 5.7 has electronic throttle the cruise is also electronic...

I have taken notes on yours and T-Muns swap and hopefully something will be figured out soon. Unfortunately, I cannot really do anything right now considering I am thousands of miles away, and, my swap still has some time to go. My 4.7 only has about 165k miles and less than 10k miles on the heads. So I can only study and reasearch what everyone else has done. Thanks to all of you guys who started this swap and made just a little bit easier for people interested in a hemi swap.

Hey D~ Hows the 04' Harness coming along ? Hopefully well..
I just read this whole thread again. I forgot , we have the same truck..02' Ram..I hope you don't run into the same wiring problems I'm having with the A/C and cab light. I might need a little hand figuring it out..
You did a great job on you're swap , sometimes I try too hard to help. I forget the 4.7 Daks and 4.7 Ram wires aren't always the same .. You know more about Rams than I do..Thanks for everything...

i am planning the same conversion, and take it from your post to NOT use anything newer than a 2003 hemi, is that what you mean ? Thank you

how has this project come along ? I have a 2002 dak with a tired 4.7 and am researching how to convert to a hemi ? let me start with a basic question or two, if you dont mind.
will the hemi bolt to the bell housing on the auto trans I have behind my 4.7 ?
will the oem ECM run the hemi, or is a new computer/wiring hrness needed ?
Thanks for your help

The later year hemi engine have better performance tuning options. 2003's are also known to have valve spring issues.

Mountaineer06- You're 4.7 Transmission will bolt to a Hemi It's probably a 45rfe.. The ECM won't work . Wherever you get you're Motor from , You need to also get the ECM 04' and up "OR"-ECM and TCM If it's an 03,..Personally From my experience , I wouldn't get an 03'. Hemi..I have an 04, In my 02' Ram and I like it. It was a LOT easier doing a 04' Harness in my Ram..My Dakota had a 03' ECM ~ TCM seperate..
There are a few different Dakota Hemi Swap threads out here , and each person did his a different way. Yellow-Dak made his own oil pan , I notched my cross member. Knowledge is the key to this swap.The wiring is the major part of it all , The rest is just deciding which way you want to do it..I would read them all , and think about it..It's a great swap if you like your Dak and don't want to get rid of it..They should have made the Hemi an option for the Quad and extended Cabs..If you need help , I'll be glad to help you do it..
