late model Hemi swap to 2004 Hemi truck - what's involved? - 11/15/22 03:42 PM

Hey Guys,

I have a 2004 1500 5.7 Hemi quad cab truck that I'm considering putting another engine in. What is involved in putting a 2019-2022 Hemi in the truck? Will it bolt up? Will the trans bolt up? Do I run the stock computer? I have no idea what's involved in a swap like this, or if it's even practical compared to rebuilding the existing engine. Thanks in advance for any advice!

It will bolt to mounts and trans will bolt up but from there everything else is pretty much different.

You'll need to lock the cam, change the tone wheel on the crank to a 32 tooth one from a 6.1 Hemi, and if you want to make the SRV work on the intake, wire in a controller for that.
