There is an '04 dodge with a 5.7 hemi in it for sale. Runs real good.It's a good price and it's close to home so I'm really considering picking it up. The reason I want it is for the hemi, the wiring and the computer and possibly the transmission. I want to put them in my 84 d150. I've been wanting to swap to fuel injected for some time now but don't want to go the EFI route, I want a new engine with new technology in it. My concerns are... While I know I will have to fabricate new engine mounts, I'm not sure about the engine/transmission combination. If I swap the new engine in, do I keep my stock 3 spd transmission? If I put the new transmission in it, that would mean A LOT more fabricating and modding. I have read online that the stock transmissions that came with small block LA engines are compatible with late model hemi engines. Can anyone confirm this? Also, I understand I will need the complete wiring harness from the new truck to make it a lot easier. But beyond the wiring, computer and sensors, am I looking over anything major that I may run into? I am dead set on fuel injected over carbureted and I would really love the efficiency and responsiveness and drivability of a new hemi.
