You need a intake manifold, carburator, vacuum advance distributor, balast resistor and wiring kit.

Unless you're planning on using a mechanical fuel pump (and seeing that it's a TBI, it may have a short-shaft cam like the Magnum, thus the usual fuel pump eccentric will not fit without a true LA cam or a modified ecentric kit -Hughes engines sells these) you'll need a single inlet, dual outlet fuel pressure regulator. If you have an overdrive, you'll need to wire in a toggle switch to activate/deactivate the OD as you like.

The Mopar Electronic Ignition Kit has instructions on how to wire it up with the computer. You will need a carburator and the MPP kit. I'd leave the stock fuel pump and just put on a pressure regulator. The instructions say to leave the computer to opperate the cruise, emitions, the overdrive, etc.

Yeah, I have a 318 TBI and I want to take the tbi set-up off and put it on my old 360. I like TBI. Starts easier in the winter, too...no pumping the accel, no fast idle cam to worry about, no choke, etc.

Agreed.

Yes, EFI is terribly functional.....coldly efficient. Rather lacking of character, though. And I hate to break it to ya, but we have an '84 that fires up immediately, and runs fine in cold weather. It was originally a New Jersey truck, so you can bet the choke works properly. The thing just flat out runs great. I clearly see and reap the benefits of EFI, but I prefer carbs.

Nothing wrong with a properly running carb, but even a half assed efi runs better than a carb for wheeling.

Can't agree there. I've experienced half-assed EFI's. They tend to spew gas, miss, and act up in general. Which sensor can you run without in an EFI? There are advantages on both sides, but can anyone tap on a throttle body with a screwdriver handle, and get home? The EFI has proven very reliable in general, but when it quits, it quits.
