HI guys, I have lurked on here for 2 days reading up on installing a 2008 5.7 hemi and 5 speed auto into my 72 Swinger.

There is a lot of info and I cannot make heads or tails out of it.lol.

Is there a definitive thread that address's what is required to use to make my combination work using oem donor parts?  Can I use the 2008 300c underhood harness, engine harness, ecu, and the trans tcm without spending money I dont have ( retired, fixed income) ?   I do not want to u$e after birth part$ if at all po$$ible for the engine and tran$ control.
I have lots of time and little money along with liking to do it myself .

Thanks for the help. SOF.

DIYHemi.com has information on what to do with your harnesses to make them work.

You can also try the board forabodiesonly.com  There is a lot of information on that board concerning the swaps.  If you don't get any help there, go on Facebook G3 Hemi Swap page and look for a guy named Joe Mauro.  He did the swap in a late 70s magnum I believe and used most of the donor cars parts.  Others there will help too.

Tranny, is it a NAG1? Then you will need some parts. I'm doin a 6.1/NAG1 in my Challenger. Using the stock ECM, TCM, ABS modules but modified by Hotwire Auto.
