'89 460 What Are The Differences?!
Hello, my fellow horsepower hungry ford guys. Here is my delima. I have a 2WD
'78 F-150 Ranger. It is a daily driver with a really nice body for a daily driver. It has a 400 in it now with a C6 behind it. I pulled the motor last spring and put a new bottom end in it. It runs ok, but I have never really been fond of the 351M/400 motors, so I have been kinda looking for a 429 or 460 to drop in. I have recently come across an EFI 460 in an '89 F-350.
It only has like 60000 miles on it and it runs great. The frame is rusted out on the truck. I would like to put this motor in my '78. The problem is, when I started looking for intakes, etc for the 460, they all said "will not fit 89-92 460." What is different about the later models 460 with EFI? How hard is it to put a carb setup on one? Did they change the angle or the cut of the heads or what? Please let me know if you know anything about this. I really want to put this motor in, but I don't know if it will be more trouble than it is worth. please help me!

the carbed intakes won't fit, the bolt holes don't line up and I believe the FI ports also line up differently but they don't cross, although you can swap on a set of earlier heads and then use the carbed intake and use the short block from that truck if you want to.

As mentioned the EFI heads are different than carbed heads. The exhaust ports are even different so one would have to keep the EFI exhaust manifolds with the EFI heads.
Another thing to keep in mind is in 79 the 460 went from internal to an externaly balanced engine.
If you were closer I would swap you carb parts for EFI parts but the drive is a bit to much.

Why not just swap in the '89 460 along with all the EFI stuff so you have a fuel injected motor in your '78? Even in stock trim, the EFI 460 puts out way more power (245hp, 395lb-ft) than your 400, I believe you'd be happy with those power gains, while leaving the 460 stock.
Also, I'm not sure where your looking at intakes at, but a carb intake will not fit EFI heads, regardless of if they are E7TE's or F3TE's ('88-92 or '93-97).

As I stated before, I think you best option would be to just use the EFI460, and leave it EFI.

I guess I am just scared of the EFI in my 78. I have never Attempted such a change before. I have always gone from carb to carb or from efi to carb; NEVER carb to EFI. How much would be involved? would I have to put the whole brain, sensors, computer, control modules, etc. in there? How hard is such a swap? Has anyone on FTE ever done such a thing? I don't neccesarily hate the idea, I just don't know how to go about it. If I could just swap a few things, mabye wire in a harness or two and throw a control module on it or something, I wouldn't mind it. But I know it is not that simple. Where would I start something like this? I know if it were carbed, I could just change my motor stands and mounts and go. If I were to leave EFI on it, could I still use my factory cruise control setup? factory gauges? Thanks for all the help, by the way.
