Brent can hook you up, but I will tell you, there is no "full" EFI setup.  They all take some modification, additional parts, and some thinking, much more than I wish they did

Not trying to hijack your thread BUT I happen to be in the same boat. Any Idea what cam you would run in your 428 set up?

Get the stealth EFI from holley. It looks just like a holley carb. And then get the drop in pump for your tank.  Change a few rubber hoses and use your stock fuel line  other than electric hookups it’s that easy !!! It will still take a little “programming “ but that is a LOT easier than you think   I have personally done this to a 70 Mach one!

I run FAST ez2.0 with an Aoromotive Stealth intake pump system. I use a DuraSpark Distributor  modified to look like a dual point ,welded for no advance. The distributor  is set up so the pick up is adjustable to phase the rotor . It is backward and a bit of a pain to set up but has worked very well for 9 years.MSD box.

I like the new Holley stuff and I think for the money if I was doing it again I would go with that.

Don’t waste your time with an external pump.
I started with a Tanks Inc internal and it did not work 100% for me (suffered pick up problems with less than 8 Gal in a Mustang tank) Would not work for auto cross below 12.
My current Aeromotive will run 21.6 gal out of a 22 gal Mustang tank without a hick up then shut the engine off when you pull into the gas station.

I have done many variations of EFI now - and can pretty much match Summit etc.  The throttle body self learning systems are OK - the Holley seems about the best one right now.  All of them are very much reliant upon the oxygen sensor - and are super sensitive to any misfires or larger cams that contaminate the exhaust at idle.  The swooped systems (xFI,BS3, etc) are far more flexible and controllable, but they expect the user to have some tuning skills.

I hate to be a broken record, but I noticed I forgot to put it in the original reply.  Be sure to think about coolant temp access, not many talk about it, but the FE has a single port unlike Chevies that have them all over the engine. 

People eliminate the heater, sometimes put the original gauge in the gooseneck, Ford makes an inline heater hose fitting that takes a sender.  In a Victor and any other time i can, I weld in a dedicated second bung.  RPMs and other intakes it's not as easy.  All sound options in the right application, but the time to think about it is before you bolt it on.

So Barry if I'm running a .600+ solid roller, I will have issues on the street at idle and would require a swooped system? Like the idea of a holley carb decoy. Thanks for your input.

62FG, my FAST system has a pretty good Hyd Roller from Brent,if the idle o2 isn’t perfect it at least is not killing plugs,I honestly can’t tell you how long they have been in the engine.
Going down the road I run 14.2 on 100% gas 13.3 on 10% ethanol (14.7x.9)
12..8 wot/ 12.0 10%.

Idle I just leave @14.0 it is sort of my base, if I fill up I can tell if I’m still on 10% ethanol or I got less. The correction goes way off. It’s easy to correct and car runs fine.

I’m running a Performer RPM,to make it work I run a 1” open spacer.
If you can use a single plane intake,an old Street Master would be good. Current Victor or TFS. I’m thinking of cutting the divider out of the RPM.

More specs on the cam would help more.  Overlap, ICL, and duration mean more than lift. Overlap basically will give you a decent idea of vacuum, and duration and ICL can predict somewhat when it clears up.  However, lobes and builds are all different, so it's mostly an estimate.  That being said my 489 is .600 lift and EFI since 2009, but its a solid flat and not that big.

Remember, you can get anything you want at Alice's Restaurant...with the right EFI kit, you just come in and out of open and closed loop when you want.  However, typically I like to hold a regularly streeted EFI build at about the vacuum levels a "no-can" power brake system would run.  That tends to be 12+ inches of vacuum.  If you do that, generally the EFI does it's thing pretty well once the engine has some heat in it especially

In my truck 461, I went with a mild HFT cam, 280/286 @.006 230/236 at .050 112 on 107 to match a 4x4 use, power brakes and EFI, in the Mustang it's 286/294 @.020 242/248 @ .050 110 LSA on 106, but it calls for .027 lash and I run it at .014, so it's a little bigger than it seems, and no power brakes
