Just wondering if anyone has ever put a 4.7 into an E body or any older mopar for that matter. I always thought it would be cool to put a supercharged one into my 70 cuda and still keep the fuel injection and so on.

See Resto Rick's website. He's doing a 68 Plymouth vert with a 4.7.

I have one in a 4900+# Ram 4dr 2wd, with a 392 gear and 20" A/T tires. It burns and turns them real good for a stock 287ci engine. With a A-B-E body weight
it should fly 12-13s in the 1/4 IMO. Excellent street torque/rpms till 5 grand, then it falls on its face.

Here's RestoRick's Web Site, but it doesn't have much info on the project. Have there been any updates?

I think this would be agreat little engine, too, and I'm keeping my eyes out for a good opportunity on a late-model one. The 2008 models got a pretty significant upgrade, and make 303hp @ 5650rpm and 330lbft @ 3950rpm. Those are almost the exact same numbers that my warm 340 make right now, and I'm sure thre would be a significant mileage increase due to smaller size and roller everything. The 4.7 will bolt up to any LA bolt pattern trans, but it's got (IIRC) an 8-bolt crank flange that is NOT the same as the old Hemi 8-bolt flange, so manual trans applications will require a custom flywheel.

Keep us posted!

I just found this post...

I'm finally getting settled in my new place to start getting back on this project.
I'm at a point where I need to sort out how I'm 'gonna run this.
Possibly megasquirt and a trans controller.

I spoke with a Chrysler tech who said he'd done a couple with using the factory harness and weeding out the emissions related plugs.
I can't remember what he said about trouble codes this would generate... I'm guessing it'd run in a limp mode?

It would be nice if there were a "plug & play" harness like you can buy for Chivy's.. from someone like Painless, etc.

Rick

Agreed... I'm not so concerned about cost as much as being able to figure it out and get it sorted out correctly.

Is the megasquirt the only aftermarket EFI controller available? or the only one that would work?

Thanks,
Rick

Tonnes of EFI controllers out there that'll work for both fuel and spark. I only bought a megasquirt because it's the cheapest efi controller on the market, and the only one that I could afford.

If you're going to run an essentially stock system anyway, why not run the stock ECM/PCM if you can? No tuning needed on a stone-stock engine/trans, you just need to convince them that they're in Durango/Dakota/Ram/Whatever they came in originally. No reason you couldn't install the emissions items necessary to keep the ECM/PCM happy. There's not much to be gained by ditching the converters, especially if you go with a couple decent high-flow units. For that matter, you could go with just one in a single 3" pipe and either split to duals after the axle, or heck, right after the cat. A buddy of mine just did a similar swap with a new Hemi in to his 93 Ramcharger, and it turned out to be a great package. The only thing that doesn't work that used to is the cruise control. He thought he could learn to live without that...

Hi Clair,

Mine is from a 2002. I checked out schematics in the factory manual (CD) and it seemed to be tied in with gauges too... other things I can't recall as well.
(it's been awhile )
To get all the emissions pieces might be a nightmare too. I've considered picking up a parts truck to rob parts from too, but it seems I'd have some pretty serious $$ tied up in that route.
I suppose a late model boneyard is an option too.

I'm all ears for any suggestions...

cool on your buddy's Hemi into the '93 Ramcharger !

I'll see if I can get some info from him on how the gauge output functions were handled. Seems like they wouldn't be critical since they're "probably" just reporting info for the gauges to show, but I have no idea if that's really the case. Seems like I remember the whole Hemi/PCM package being nearly stand-alone once the redundant/useless stuff was culled out.

Clair

Just remember though, if you want to do any HP mods after that, you will be at the mercy of the few who can reprogram a stock ECU. Which from what I've seen is a very poor substitute for tuning your engine yourself. But if you keep it bone stock, it will work great because all the tuning is already done for you. I've done the stock ecu retrofit twice now, but I won't do it again. In the long haul, it's just not worth it for me because nothing stays stock forever. Then your kicking yourself for investing the time/money into a non-user tunable system. But either way... good luck.

Yeah, the OP is probably going to need to go aftermarket if boost is in the plan. Duner managed to boost the snot out of the 4.7L in his Dak, but I forget how he managed the extra fuel. I think I remember that it was some sort of external FMU, but I've slept too many times since I discussed it with him. Sounds like RestoRick may be keeping it stock for a cruiser, so maybe the OEM stuff would suit his needs. Although I'd love to have a stock 303HP 4.7L under my hood, I don't know if I could keep my hands off it, either... At least I wouldn't have to worry about running the auto trans, too.

Clair

you know I have been thinking about aftermarket computer controlers.
I understand now that the base stuff seems to be the same, just the connectors are wrong.

Not saying it would not be a pain and look ugly, but when painless comes out with the efi for the 5.9, couldn't you just cut the connectors off the stock harness and use it with the sensors they use and run it? Might need to tune it still, but it would be the right firing order, and close to the right programming,to at least fire it up.

I'm not sure, but I don't think the 4.7L has a distributor, so there would have to be a little work to get the coil-on-plug ignition to work, although the Mag dizzie doesn't really do anything but give the spark a place to go. Probably something like one of the LS engine controllers could do the trick, though.

Clair

Well...

While a basic cruiser is the plan, I could very well play with it more down the road.

What are some EFI controllers worth looking at?
I've googled and come with a bunch for motorcycle applications... also the multisquirt.

Clair, "LS engine controller"... what is that?


Rick

You would think that F.A.S.T. would have something. How about ACCEL?
I'm really interested in this little project, I always thought the 4.7 was a torquey engine in the Dakota. With a little tuning, should run 350 hp easy, I would think.

Rick,
The "LS" engine controller is one of many/any that are capable of running one of GM's LS-series engines. These generally have sequential injection, distributorless ignition, coil-on-plug ignition, etc. As with many GM control systems, even the OEM parts have a bunch of aftermarket support and some tuning capability. I think an LS-1 system was used early on as a stand-alone system to run the new Hemi, so the 4.7L shouldn't be too hard to adapt, either.

Clair

Cool.. thanks... I'm looking into it.
