    Aftermarket EFI on 460 cliff notes?

    I've got a couple potential projects on a back burner, 70s Ford's sitting for some time with 460s, ones a camper van, other a shiny Friday night truck

    I figure either rig will need fuel tanks removed, everything flushed, and carbs rebuilt, mechanical fuel pumps replaced (I've lost an engine to a dried out diaphragm dumping fuel), carbs got expensive, and i never was good at them, so stand alone efi might make sense

    both rigs should have duraspark

    looking for bang for buck

    recommendations?
    fitech?
    holley?
    something better?

    460 efi guys can take an 88-97 harness and turn it into a stand alone. They can also sell you a pre built one. That should probably be your best option over the aftermarket tbi units.

    Just grab heads intake and harness off a fuel injected truck and they can set you up with a stand alone for like 650 bucks.

      And have a shitty computer that hates mods.

        What? I am not a fuel injection "expert" by any stretch, but my personal experience and most things I have read say the factory Ford fuel injection is a better setup than the aftermarket stuff. Multi port > TBI, and the factory parts are more reliable, cheaper, and more widely available. You definitely want a mass air setup since it will "adapt" to mods without a need for a tune unless you start running bigger injectors instead of a speed density system which will have to be tuned any time you make any major changes to the engine. Sure EECIV has some limitations compared to newer stuff, but it definitely isn't garbage. I'd bet you could do an EECV (OBD II) setup without being too crafty if you really want for the tune-ability.

        Regardless, for a stock setup, the factory EFI stuff (speed density or mass air) is a no-brainer.

          The factory Ford computer can be tuned just as well as any of the options the op listed. There's no shortage of aftermarket tuning options available for early Ford electronics.

          Sure you can use megasquirt or something fancy and go all out with it but it really depends on your budget.

          For my money, in the sub 1k range the factory efi setup definitely gives you the most bang for your buck.

            Having built a 351with a factory computer, I would go with a TB stand alone next time. There are a few places with a Dyno that can work on them, but if there aren't any local your just in a never ending struggle.

              Was this a speed density setup? Was the guy doing your tuning familiar with Ford EEC? There a quite a few guys who are pretty good at tuning via email if you can send them log files.

              Again though, the OP hasn't indicated whether the engine will be staying close to stock or not. If he isn't planning on making more power than the stock injectors can support, or running a really nasty cam, then just put a factory mass flow EEC setup on it and be done with it.

                I like Mega/Micro-squirt personally, but to run either the way I'd want to do it, you'd probably be swapping to a multiport intake, buying injectors, fuel pump, wideband O2, TPS, crank position, coolant temp, intake air temp, MAP, at least two ignition coil assemblies, building a harness... even if you can junkyard most of that, you're probably looking to start off spending at least a grand, and building a wiring harness. If you can't junkyard it and/or aren't comfortable with building a harness, it'll get much more expensive in a hurry. Drop-on TBI (Fast/FiTech/Holley/whoever) will probably be cheaper, but may not get you ignition control, whether you want that is another (related) discussion.

                  Good point on the ignition control with the aftermarket EFI setups. The factory Ford stuff controls ignition too which is nice in my opinion since properly curving a distributor is a pain in the ass, especially with Ford stuff.

                    Carbs are getting more expensive and self learning efi looks to be getting cheaper

                    I'm just looking to improve the driveability of an old stock 460 with minimal work and minimal expense over a new carb and replacing stick fuel system

                    picking up minor performance and fuel economy is a plus

                    If I was going to swap heads and such, I'd probably just start with a different powertrain altogether

                      No, mas air conversion from a mustang. I forget who I had doing the tuning but it was sending him the ECU. Constantly chasing issues, was never "right". Trashed it and went with a stand alone system. Light years better. But for the time and money I wasted on the stock set-up, I could have bought one of the new TB set-up's. Running a 14" air cleaner would have been nice to.

                        In that case I'm sure any of the bolt on tbi units will work fine. The only word of caution I have is that a lot of them use inline fuel pumps like the e2000. Keep a spare because they tend to hydrolock and burn up.

                          Also, use a single plane intake. Dual planes fuck with some of the TBI systems.

                            Once upon a time I had an early bronco somebody dumped a ton of money into, but cobbled together a cobra/ lightning /mass air setup on using a e2000, I'm going to avoid all that, this project would start with a new fuel tank and in tank pump, F that inline pump

                              I'm doing a tbi conversion for my Chevy, I'm using the factory in tank pump. I decided to go with stock efi so it is easier to troubleshoot and get parts for in 10 years.
