I cannot strongly recommend @HemiDenny K frame enough. It is a game changer. Saved me countless hours of both labor and frustration. He is active on this site and if you call his Company the chances are super good he will be the guy answering the phone. He endured countless questions from me with both grace and professionalism. As for the feint of heart comment, I am not an actual car mechanic. I am just a farmer that is handy with a welder. The swap was the ragged edge of my abilities. Both electronically and mechanically. Again not to whine but the industry supporting a Hemi swap has evolved a lot since I did mine. You will still need to fabricate a million of your own parts and provide creative solutions to a myriad of problems. My build thread on here is titled 72 Demon Hemi swap or something like that. I would have to search it to remember what I called it! Hah! The LS guys got it so easy! You gotta earn a Hemi swap!
