5.7 in a '97 Ram.

Just get an 05 ECM and a harness from Hotwire. It will run better than carbed. Just tell them what transmission your using. An 05Ecm will run about 75-100$$$$. The harness about $1300. The carb and intake and control will cost you more. Your current fuel pump may be enough to run it. I have no idea what fuel pump is in a 97. Call Hotwire, Chris will tell you what you need. Keep your original harness for everything but engine HOMEmanagement. Your dash instruments may be a challenge. Give them a call he can answer everything for you.
