What configuration intake are you looking at using?

If you have the intake I'm thinking the biggest decision is going to be which ECU.....? When my intake was done it had injectors too small for the application installed, and the lines weren't done in a way in which I could leave on the car, the throttle bracket was made twice, once by the EFI guy and once by the engine builder, neither bracket would even work. There was no return provision for the fuel system whatsoever and somehow it was claimed it ran on a dyno. Who knows... What I am saying is.... if I did it again I would do the intake conversion myself. No doubt about it! Nothing worse than paying to have something made, then not liking some things, some things don't work etc so you HAVE to remake things you've already (over)paid for....

This is what I did myself, WITH a proper return system.... and correct injectors.....

it's an INDY set-up with the fuel rails going directly into the manifold. I don't know much about them on old cars, but seems like it would be better than my edelbrock 800 and m1 intake
i think it would look crazy hacked on stock looking muscle car, plus you would have to run all new feul system like race car all braided lines/an fittings, custum cell with efi pump, and return lines, then figure out were the mile of wires/computer are going to go? would be cool on old street rod. you can buy dual four intake/carbs/cleaner pretty cheap now id go that route,nothing sounds better than hemi with both carbs wide open
Looks pretty hacked up to me.

My hemi is fuel injected. If you don't like quick starting and smooth idling than stick with a carb. Tim at FHO has a 2-4 fi setup that once the air cleaner is on you would never know it was injected. The biggest thing is the system that you run. I have a Fast xfi but if you get into buying a older antiquated system the tuning headaches wont be worth it. Fuel injection is awesome.

would it add any more power or just make the power available more readily available/efficient. fuel mileage?
More power depends on how good you are at tuning a carb. I will tinker with a carb to get everything I can out of it, but most systems, efi vs carb, are within a few ponies. The advantages of the efi are super easy starting and idling, along with far better milage. There are systems out there that are not a lot of hassle. The new EZ-EFI from FAST is one that is self learning, and does not require a laptop.
I have been running EFI on Hemis for some time now, and like anything else, a well designed system will keep you away from many of the issues that can plague an engine converted to EFI with the wrong componants.
I run the older classic FAST system on my hemi, and would not trade it for two carbs. The system you saw for sale is an Accel DFI system, and they can be difficult to work with. Its a good deal price wise, but not easy to set-up or tune.

OEM efi cars didn't run braided lines or an fittings, so I don't see why you bring that up. For EFI pumps there are several options that use a stock gas tank, fuel cell is not needed. If adding one return line is like pulling teeth to you, you probably don't know how to tune a carb anyway. Yes you will have to see the injectors and fuel rails, but if you run your wiring carefully and run an oval 6-pack style air cleaner you can hide most of the EFI hardware/fuel system, even with a multiport setup. And if laid out with care and combined with your stock wiring harness, the extra wiring for the efi system need not be clearly visible. Likely won't make it 100% invisible but you can hide a lot of it.

looking at an EFI unit for my hemi and would like some opinions or experiences with EFI on an old school engine.
You should checkout the photos page on my web site. www.fastmanefi.com
I've done a "ton" of EFI Hemis. Probably more than anyone else. Personally I like the new dual TB manifold from Stage-V. Let me know if I can assist in any way.

Be aware that some systems don't work well with too radical of a cam. So If you are going in this direction, ask to see if it will run well with your cam.

Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first.
Life was a little easier when I was just a wrench.

was just trying to prepare the guy for the radical changes he will have to do,he dosent know thanks why he was asking.so you have the capability to make your own stainless or plastic quick disconnect efi lines? how can you ass-ume i dont know carbs when all my cars are dual quad hemi or 440 six pack all rebuilt by me. lets see pics of your super clean efi install on anything.....nice winter car in sig

You appear to have absolutely have no idea what your talking about Why would you need quick disconnect efi lines? The only major changes to the fuel system is a return line,high pressure pump, and regulator Just look at some of Rich's installs if you want any idea of how neat efi systems can be. Don't keep your head in the sand when it comes to F.I. The technology is incredible.

yes ive looked at them for years, now the tech, and manifolds i want are finally here have talked to tim-b about the 2x4 efi on stage-v street hemi intake allready, wont be long before i convert a carbed hemi over
