EFI for a FE
I have been planning to restore my son's 68 F-250 for the past year. I have desided to build a 410 for the truck and have given some thought to trying to put an EFI system in it. I went to the local parts store and found out that Edelbrock has a manifold for the FE but it is rated to run at four to nine grand. I hadn't planned on using it for oval track use. Is there anything out there that can be used for a daily driver and for pulling a boat and camper?

there are plenty edelbrock manifolds for FEs but some times they dont like to seal. besides the stock 4bbl manifold will out flow a edelbrock performer. for a daily drive you want a dual plane.

Just find a decent single plane and have the injector bungs welded in, and fuel rails mounted. My EFI FE was in the July 2004 issue of Hot Rod using a similarly altered Dove intake. The EFI makes a single plane much more street friendly - - most OE EFI intakes are single plane.

Hate to disagree with '76, but if you are planning to put EFI on the FE, then a good choice for an intake is the Edelbrock Victor. Dual plane is great for cards, but with injection you don't need the scavenging the dual plane carb provides (or at least that's what someone on this list said once).
The RPM's listed on the Edelbrock intakes are for carbs - they don't really apply if you are going fuel injected.
Fuel injection with will give great street manners and good torque.
There's another thread on this forum right now about FI.

Iwould get a edelbrock RPM because it will out flow most especially the stocker, and throw a holley commander system on top like Rusty uses. That would be the simplest but if you wanna throw money at it then go for the slick custom MPI style and have the victor drilled and bunged for injectors.

i have a mildly built 390 with edelbrok heads, a performer intake(i know i got it befor i knew any different), and a .519 (or so) cam with the holley commander but im still trying to tune it right. if you get the commander and plan on tuning it yourself, plan on it taking a while. i have a question... could my MSD ign. be causeing me to have issues tuning? ... i am thinking no (since it can be set up to run with it) but i have to ask incase anyone has delt with it. Rusty have been a great help so far thank you
PS i have really posted much here but i read a lot of your guys posts very helpful thanks

You will have the same tuning issues with any EFI system because you will have to establish your fuel curve and timeing ECT ECT.......Thats just the nature of the efi game when your dealing with non efi motors. Or you could pay someone to do it for you but that wouldnt be any fun.

the only thing is that the commander dosent have anything to do with my spark it just reads off the tac out put from the MSD... will that make it harder or easier to tune(without dealing with spark)? yeah i really dont want to take it to someone else id rather do it my self(cant afford to).

You can mount the map sensor anywhere. Mount it 50 feet from the engine. Makes no difference. For the intake I would stay dual plane intake no matter if you go port or throttle body injection. There is a big difference in the way a port injected engine behaves with different intakes. Go dual plane for a truck, like the performer RPM. Look at the runner lengths on a stock EFI 302. A dual plane FE intake has a good 6" more runner length than a single plane. It is very difficult to convert a dual plane FE intake to port injection that's why all the EFI intake builders recommend going with a single plane. I can convert any dual plane intake if you're looking.

My Engine Masters piece made 672 lbs/ft on 91 octane with a single plane and a 1050 carb. Port size and shape, coupled with a well matched intake, and cam will provide plenty of torque. FEs aint lacking in runner length - - especially at the corners...

Where in the RPM range did your engine make 672 lb/ft and how many cubic inches was it? When building a practical fuel injected FE for a truck that will be a driver and towing anything you need the most torque around 2500 rpm and peak power around 4500.
I don't have an accurate torque number on the fuel injected 390 in my truck, but it will give a new cummins a run for it's money and match it in gas mileage. With an RPM intake 901 cam and 700 cfm throttle body and it's just batch megasquirt injection.
