I made this video to show that you can DIY Hemi swap Jeep Wrangler without buying a kit. I did this swap buy buying a whole donor Jeep Grand Cherokee and a few parts from Jeep Speed Shop. After I sold everything off of the Cherokee, I had about $500 in the drive train. $400 for the radiator, $500 in exhaust, $340 in JSS parts, $500 in miscellaneous parts, fluids and gaskets. So somewhere between $2,000 and $2,500 for the entire swap.
