This is 6K oem Pullout engine and 8hp9o trans with all harnesses excessories ecm ect. Dart has Gerst coil over front end and Dana rear. Looking to see how hard of a project this would be. Any knowledge or advice would be helpfull. Have some Fab skills but have not purchased new motor yet. Have no experience with Gen III.

its been done but the hemi is really wide and engine bay in an a body is really narrow.

For your first time you might start off with a junkyard 5.7 and see how it goes. Once you get all the work done to drop the 5.7 in then it would easier to replace it with a Hellcat.
