Mass Air EFI Conversion for 390 FE

The search is not working right now and I didn't see this discussed in the last couple of month's postings so I'll give it a go.

Can I take my 1968 F250 with mildly built 390 to a Mass Air EEC VI? IF so what year and truck would I look to get one out of?

Are there fuel injected throttle bodies in standard 4 barrel size that I can mount on my Edelbrock performer and that will work with an EEC VI box?

What kind of distributor do I need to run?

Sorry this questions are so basic, but I've been looking in to fuel injecting this truck for a while and only recently realized that all modern Ford trucks are Mass Air injected. It seems like it would have to be a lot cheaper to use something like TwEECer than pay a lot of money for an aftermarket EFI setup like TEC3r or Mass-Flo. Why is it that almost all the aftermarket fuel injection systems are speed density?

Yes, for the FE it's almost $4,000. Why is it so much money?

The FE series never had EFI from the factory, so you will have to modify an intake to accept the injectors. I only know of two or three vehicles that came with throttle body injection and mass-air, and all those systems are too small to run a v8. I'm not saying it can't be done, but you'll be below the level of a well-tuned mulitport speed density system.

I do not know what dizzy the fe's used, but if there is any TFI dizzy which can be dropped in there, or even modify your dizzy to use the guts from a TFI dizzy. having the injector bungs put into a intake is not that expensive. I would say I am around 2k into putting EFI on my 400, and that is including the tweecer to tune it.

I have a victor ready to be modified for multi-port - I just figured throttle body would be an easier first step. I have a MSD distributor in there, but the Mas-Flo kit comes with a Mallory - Is that what I need? Can I do fuel only with an EEC VI?

I don't think it will work as a stand alone fuel controller. I do know that you can modify a Megasquirt controller to use a mass air sensor, though. I think the info for that can be found in the Yahoo discussion group for Megasquirt.
