OK really, how hard is it?

I have a 351 EFI with bad crank bearings.

Can i put the manifolds, and computer and everything else onto my carburated 84 351?

What all does the computer hook up to, besides the motor?

its basically the same engine. the computer controls the efi, you will need to swap distributers thats it. I just went from efi to carb in my 87 bronk.:usa :usa

you may need to use the timing cover from your current efi motor onto the 84 motor.

Re: EFIswap

Ok what about the fuel pump? Do i just mount up the old one up? will there be a lot of re-wiring/splicing ?

Oh the confusion? You need to put your trucks details in your sig.
I can't answer any questions by guessing what Vehicle you have or want to swap engines on.

efi swap

if your using the same efi that was in the truck then all you have to do is put the efi on the donor motor, and swap the timing cover. if your going that far you might as well put a timing chain on, swap the cam for a little more thump. good luck Jay

I can just put all of the crap from the donor, on to my exisiting motor, but what aboput the fuel pumps? Do i have to put an electric in the gas tank, and one on the frame?

will these be somewhat of a direct swap?

Is there a real write up somewhere to look at?

Ok, so you have a Carb'ed 351 in a 1984 Bronco. And you want to put in a EFI 351. Understand now :thumbup The rest of these yahoo's are confusing you :twak

Everything will bolt on / in your truck. The hardest problem will be wiring it. Here si the closest to a write up on this: http://fordfuelinjection.com/setup.html

For the fuel system. I'd look at the pictures on Steve83 site and get stuff from a donor in a junk yard

Thanks that helps out a lot.

The donor truck had an e4od is that going to mess anything up, on my bronco with a manual?

I have the entire wirring harness, from the parts truck. from there will i only have to splice power to the EEC or is it much more envolved?

No Problem :thumbup

Yes that will mess things up. Also makes the harness have more wires than you need.

You have to tear that harness down and explore which wires need to be slpiced into the trucks body harness. It's usually a big project for the first timer
