I heard from someone that you can turn a carbed 460 into a Fuel-injected 460, by taking everything(intake, injectors, wires, computer) off a fuel injected 460.

Will this work?

Has anyone done this?

Can they give me a list of things that are needed from the donor vehicle?

What needs to be installed where?

I would like to do this on my 460, but want to find out what the details are first

 

That will not work unless you use the heads from a F.I. motor as the intake side of them is different.

 

It is possible, but like Brian said you need to replace everything from the heads up, and instal the high pressure fuel system. If you do this you WON'T make more power, you may loose power, but the driveability is greatly improved.

One other thing you'll need to change is your exhaust manifolds. The EFI heads have had at least three exhaust design changes since their start...I have a late 1989 engine, the exhaust ports are almost square and are quite small. Deen

What are the power differences between the, say 86 460 with a carb, and the '87 with FI?

Always been curious...

 

hmmm, sounds like i am in for a treat, if i decide to do it. Will the heads that i need fit on a 71 Lincoln 460 block or will i have to find a late model block to go with the new heads?

 

none of those heads your planning on using are open chamber are they?
you don't want those

The deck heights for these 460 blocks changed as follows:
1968-70 -- 10.300 inches
1970.5-71 -- 10.310 inches
1972+ -- 10.322 inches

If I remember correctly, both the carbed '87 and the EFI '88 were 230 HP @ 3600 and 390 TQ @ 2000. The big difference is not that you'll lose power; as you can see, the numbers are the same; but that you'll lose the possibility of reasonably priced improvement. With the carbed 460, put a better manifold on there, good 4-into-1 headers, a good 750 cfm carb, and a slightly more a ggressive cam and watch 230HP/390TQ power turn into 300HP/480TQ power for less than a grand. Do that to an EFI 460 without seriously modifying the computer's programming and spending serious money on custom programming sessions (could be up to $500 or more) and you'll be lucky if the computer will even bother to run the engine. And that's assuming you can even find that stuff for the EFI 460. Aftermarket support is weak, expensive, and not getting much stronger.
