    The engine swap from a carb'd 318 to a 5.7 hemi is finally (pretty much) done. Just getting O2 sensors put in the exhaust and kickdown linkage adjusted, some other small things like that then it's ready to go. I kept the 727 transmission. Will make a video in a couple days to show you guys. It's just in time for the colder weather which will be nice not to deal with stalling and unpredictable carbureted issues this winter. I will miss the durability of the 318 but that's about it.

    The majority of it was done by a mechanic who I know in my town. I was able to stop by a few times each week and help out where and when I could. I definitely learned a lot. I have a few pictures but nothing extremely detailed. I could however answer any questions on how it was done though

    That's Awesome! How much of the truck's original wiring is integrated with the new PCM? Which adapter plate did you use to mate the 5.7 to the 727 and are you still using the original accelerator pedal?

    I bought a wiring harness from hotwireauto.com specifically made for putting a 5.7 in an old Mopar vehicle. Obviously none of the lighting and horn wiring etc was affected by this, but pretty much everything else was replaced. It came in a fully labeled bundle of wires which made it (sort of) easy to just plug in. I used a flexplate/flywheel made by Mopar performance I believe, it's specifically made for coupling the 727 with the 5.7 engine. Using the original accelerator pedal yes.... but not the original throttle linkage. The cable still leads from the pedal up to the engine bay, but then I bought a bell crank assembly (found only on 03 rams) that basially converts the mechanical workings of the throttle pedal and cable to a computer controlled throttle. The bell crank assembly is essentially the bridge between a mechanic input, but a computerized output.

    I was the mechanic's "parts hunter" and researcher, so I figured *most of this out on my own and online. Then he made it happen using his knowledge of installation etc.
