Licorice72, I totally understand the decision to swap in an LS. I am a born and breed Mopar Man, and have a 1971 Plymouth Roadrunner. Which I have had for 37 years, but Chrysler did not make the new Hemi swap friendly. Unless you have extremely deep pockets or extraordinary fabrication skills. The new generation Hemi is a beast to put in and expensive. New technology far exceeds the old, and it would be awesome to have a 1972 Hellcat Dart! It's a shame that Chevy and Ford created powerplants with more adaptability than Mother Mopar. This frequently puts you in a position to consider Hybrid engine swaps because they are cheaper and the aftermarket is extremely supportive. Good Luck and post pictures of your endeavor!!!
