Debating 5.7 or 6.1 swap

Talk with Modern Muscle or Hotwire Auto. They can reprogram a 2005 Ram computer and supply the wiring harness. I went thru Hotwireauto.com and he sold me a complete plug and play harness for $950 that also runs the 545RFE trans, and he supplied an used 05 Ram computer, reprogrammed for $300 (new available for $700).
