Gen 3 Hemi list input needed
I hemi swapped my D150 a couple years ago with a 2011 5.7 from a ram with a 545 transmission. I wanted to use Holley terminator x max but it will not control the transmission. I recently bought a 2018 salvage 6.4 challenger to part out and use for my duster and call Holley again and they still can’t control the 545 or the 8 speed. I ended up using Hotwire for my truck. You send them a factory ecu and they build a custom harness. If you use a 545 it’s around $1750 but if you use a nag or 8 speed you need a transmission and that about a $1000 more. Hotwire recommends disabling the mds. My truck might get better fuel mileage with the mds but on the interstate I’ll get around 20 miles per gallon with 3:55 gears. I have drove my truck 35000 miles since the swap with no issues. The only downside to Hotwire is if you need custom tuning you have to find someone that uses hp tuners and that is not cheap. The 545 went in my truck without modifications to the transmission tunnel. If it was a nag or 8 speed it would have taken some work. I think if you use a 8 speed in a duster you pretty much have to cut the torsion bar cross member into. If you use a manual transmission or a 46re you can use Holley but if you want a 545,8speed or a nag I would use Hotwire or another standalone company. The Holley mounts worked great for my swap but like everyone else said they make it hard to find headers that fit. The d150s have the same problem as a body’s if you use Holley mounts you can only use Holley header and for a body’s they only offer a manifold. Hopefully some of this info will help you with your own swap.
