Anyone done this swap or is it even worth playing with? Is all the computer and emission equipment just too much to deal with? See, my '05 Dakota got totaled this weekend and I'm deciding on if I'll buy it back to drop the drive train into something else. It has never given me any trouble and it moves.. er.. I mean, moved the truck along nicely yet still pulled around 21-22mpg highway.

BTW, since everyone loves carnage, here is a pic of my baby all smashed up. I'm really going to miss my truck.

Don't know what you'd might put the 4.7 in,but I think it's a greatly overlooked engine as far as swapping goes.It makes good power and is fuel efficient,one of Chrysler's best engines IMHO.

Ditto the 4.7 is a good running engine. It's wroth a try.

I would guess the engine width would be the biggest challenge in the proposed swap. I think a 4.7 swap into an A body would make for a great driver.

You will need to either go to an aftermarket EFI controller or dissect the stock wiring harness, wire it in, then send your stock ECU out to be flashed. As-is, it would not run out of the vehicle.

Thanks to all for the encouragement. I'll have to see what the buy back cost is and go from there. Anybody know offhand what options are available to wake this engine up a bit? I know it would end up with a set of true duals, dual cats, maybe some air filter/air intake mods, and what ever else might be necessary.

Why the flash for the ECU? If I use all the 4.7 controls and such I don't see why I would need to unless I start adding some performance mods. Am I missing something?

Hard to find a good 4.7 around Detroit area. Something to do with timing chain tensioners failing and causing other damage, I think.

Are you also going to put in every scrap of wiring from the dakota? That 05 computer is expecting to communicate with the body computer, anti-theft system, gauge cluster, all the emissions equipment, etc. Take any of this stuff away and you will have problems, unless you get it flashed. 1996+ when OBD2 came around, swapping the electronics over became a nightmare. The wiring is a lot more complicated to dissect and the computer needs to be flashed to ignore all the stuff that will be missing in your new vehicle. The 95 and back stuff can be done much easier. I swapped in a 99 engine but used 95 electronics for just this reason.

I had em comeinto the shop with holes in the VC and the timing chain sticking out.. and since the engine is out might as well service it

No, don't need to add all the extra stuff. I would love to ditch the whole emissions crap built in to the fuel tank, body, security, and whatever else isn't necessary. Who out there will flash the computer on these to eliminate the garbage?

If you don't mind me asking why don't you fix the truck? The damage doesn't look too horrible. If you really like the truck fix it and pocket some cash.

the frozen wastes...

Its really too bad that more wasn't done with this engine. No real aftermarket, never put in cars, etc. In my quest for a quick, cool-sounding and extremely efficient V8 for my 70 Challenger i want to daily drive i kept coming back to this one. Its small, its light and being a DOHC it will sound wicked with some dedicated pipes, make very good power and kill anything else in efficiency.

Then i get into the nightmare ov install, the non-existent aftermarket, and the fact that no one knows anything about them. My final thought was basically... for the work involved i'd just install a Ford DOHC mod instead. That solves EVERY problem. The way i figure... you might as well... it'd be the same amount ov work to swap the Ford in... possibly less because the aftermarket is there to solve many ov the problems that WILL arise.


Still... for what YOU have... i say do it. I wanna see it.

Pale Roader, have you seen a DOHC Mod motor out of the car? It's wider than it is long.

The 4.7 is a small, lightweight engine and would indeed make a fine A-body motor, or probably fit pretty well in a '30s or '40s Plymouth or Dodge. I'd say you either need to start with the entire stock wiring system and fuel tank, or else plan a different transmission and Megasquirt. That's just a guess.
Stock cams are assembled out of pieces and supply oil to the rockers. I don't know about upgrades.

The entire cab would need to be replaced. It crushed the dash down into the console and you can see the sheet metal buckled inside right above and behind the rear door. I would bet money it is more work than it is worth to fix.

2007 up engines are much better and make a ton more power.Little speed equipment other than turbo stuff and headers.Engine is a SOHC.Engines are very sensitve to the condition of the oil.Dirty oil = bad chains and pvc problems.
Not a bad deal for a driver but engine is very wide.Worst issue is probably fuel mileage but in an a body it should be quite good.
Fast might have a solution for the computer stuff.

Try hemifevertuning.com I think he's basically the only one out there who specializes in the OBD2 Dodges. Perhaps he can answer some questions for your. All I know is I had a complete 99 obd2 harness/computer from a dakota and I managed to dissect out just the computer and engine wiring harness part. However since I was just keeping the engine stock, it was cheaper for me to just get a 95 computer+harness from the junkyard than to have my 99 computer flashed.

Thanks for pointing me in the right direction!

Hmm, it seams as if no one has done this swap. I wonder if it is due to the complexity of it or the fact it is just a little 4.7 V8? The only vehicle I could put it into right now would be my '65 Sport Fury and I'm not sure I want to do that. My '72 Charger has a fresh 318 (less than 10k) so I really wouldn't want to pull it but I bet the 4.7 would get better mileage with the FI and OD trans. Hmm...
