TTI or Holley offer swap mounts for factory K member. The Holley moves the engine ahead one or two inches. Would work good for that Hellcat blower. They both offer the headers to fit as well. I like TTI better than Holley on that. TTI offers full length two inch primary that will still fit your factory K and torsion bars. Will need to relocate oil filter no matter who or what you use for mounts. I've done A body gen 3 swaps. Feel free to ask any questions.
