Well I'm building a 69 elky ground up frame off for a friend of mine. He bought it about a week ago and I will be tearing into it next week. He wants it done within a year!

Anyways he wants a efi 383 and a healthy cam (they all want that sound lol). Well I don't want to get to in depth on an efi set up and hedoesnt either just a simple set up and so the ez efi came to mind. He's looking for about 400hp is the ez efi able to support that without issues?

I've never done efi before so I'll be asking a lot of dumb questions lol. But I need to learn somehow right?

Do I need to do anything special to run efi as far as sensors I know I need an o2. This will be a true dual set up no X or H pipe so will I need 2 sensors one in each header collector?

What about fuel supply? Do I need a spicial pump or sending unit?

I will be residing the car with a highway 22 kit from American autowire so I should be able to get power to the system just fine.

He wants all the "bells and whistles" all the "shinnys and prettys" so power windows seats tint ac stereo door poppers the whole 9 yards!

My biggest challenge is the efi lol the rest is easy!

I'd look long and hard at a 6.0L LSX motor out of a truck before I built a 383, hard to not get 400+ HP ..........

Buy an EFI from one of the major vendors and learn about the affects of cams etc. They need to work in harmony and when the EFI does not like the camshaft you have nothing but GRIEF. There's lots of info out there on doing an LS swap and much to learn before tackling one. This is one area where doing 80% up front will let you finish with the other 20% of your time.

There's a swap sitting in a garage down the street and the owner has virtually thrown his hands in the air. Sept we are going to tackle it even though it's a Ford with a FAST EZ EFI system. Did some quick research and FAST advised that the system needed 10" of vacuum. The cam he has in there will never get that under 1400 RPM. He did not tell the engine builder what he was using for induction. So he has some choices to make. Expensive education.
