Reviving an old thread because I just did this swap. I installed a 2020 6.4L from a scat pack Challenger into a 2018 300C 5.7L. It's still using the stock 5.7L 8HP70 but with a 1320 torque converter...

Thanks guys. Just swapped a 2020 6.4 into my 2018 300C and trying to get things smoothed out.
Looking to see if anyone can share a stock 6.4l hp70 TCM calibration from a car. 1320 preferred but will take anything I can get.
Thanks
