1970 barracuda Hemi swap. 2008 5.7 hemi out of a ram 1500

[Williamraylynn]

Hello gents. I recently picked up a 5.7 hemi out of 2008 ram 1500 and am planning to drop it into my 1970 barracuda grancoupe. Any suggestions? I have questions about which harness I should go with and where to get adapters for my speedo and for shifting

Welcome aboard, can’t help with your swap but I’m sure someone on here can

I don’t know a lot but I have heard there is a lot on the truck engine when trying to swap it into our cars. Good luck.

What trans are you trying to use ?
The 5.7 swap is relatively easy , you need a stand alone computer to run the engine , not sure anything is available to run the trans , better off to use an 833 or 518

Just the factory 545RFE. Ive talked to the guys at Hotwire and I’m just waiting to get a harness now. I’m wondering if my rear end will be okay or if I should put my extra 8 3/4 rear end under the car

You're on the right track talking to Chris at Hotwire. Super nice to deal with. What rear is under the car now? An 8 3/4 will be plenty strong for a stock 5.7.

I went the aem way on both my swaps. If you go carb instead of the injection, you can use msd´stand alone ignition controller (hemi6) or
the aem infinity 3 series. it can control 8 ignition coils, and injectors. very easy to work with, and fast responce.. the aem is allso the (for now) only system that can handle the 60-2 notch crank signal on the 2013 on engines. on the older one like the one you have, would i go the FAST way - they have controllers for the engine and for the new type transmission. just finished my 70 challenger with a 2015 5.7 eagle hemi and it works…

Is but direct from mopar the CPU and harness kit. It will be new and have all he right connectors. Yes it's 1500 bucks but find a friend with an employee discount like I did and go. I just finished my 392 install. It was a tight fit but she runs like a raped ape now. 7345453794 of you wanna know anyhjng. Peter.

Decided to use the suspension from an 06 charger
