Post 460 EFI Conversion

Hi all sorry if this has been covered before. I would like to convert my 79 F150 with a 460 to EFI. First off will the 460 EFI intake bolt up to my 70's vintage 460? If so I assume I will need to use a mass-air setup since I don't believe the speed density will like my different cam, headers and dual exhaust. Since the 460 was only mass air in Calif. and NY I suspect I'll have a hard time finding parts for it in Indiana. Whould it be possible to use the 5.0 HO computer with a mass-air meter recalibrated for 24 lb injectors? Would the mustang computer work with the 460 distributer and throttle body? Thanks Dan

The '97 F-250 HDs may have been MAF in all states, but my late '97 F-350 460 is speed density.

The EFI intake only matches the EFI heads. You'll have to make custom headers to fit the EFI heads in a 79 truck. I have a 89 EFI 460 with mild cam, headers, dual exhaust, and speed-density...they are compatible. It all depends on how wild your cam is, my cam is 206 in. 212 exhaust at .050, custom built for towing heavy loads. Deen

Post 460 EFI Conversion

Does anybody know exactly what it is that is different between the efi heads and the older ones that prevents the intake from being compatible?

If I'm not mistaken the bolts had to be moved on the EFI intake manifold to clear the injectors. Thus, it would be very tough to modify the heads or the intake manifold to be bolted together. You'd probably be better off taking a carb manifold and having injector bungs welded on.

Post 460 EFI Conversion

The EFI intake manifold will fit with some mild intake porting on the head. I have 1970 D0VE heads on a 1992 460 with the stock intake manifold. The EFI intake runners are about 1/4 inch higher than the D0VE intakes, but there is plenty of casting in the heads to allow the ports to be matched. The intake has thin walls and will not allow much porting.

I have looked at the mustang ECM and a recalibrated MAF and that should work fine. Mustang folks do that regularly. I would consider going to 30# injectors though.

Email me directly if you are getting serious about this. I Can send you pics and maybe save you some time and frustration. Place F350BRONCO in the subject line so it does not get eaten by an email filter.

Regards,
John

hahah i made my own thread on this exact same topic earlier. this sucks i dont mind getting newer heads but i do mind making custom headers. thanx for the info though.

does any one know of any headers that are purchaseable to make it work???? I read on another thread that some people use fender well exit exost. Does any one make F/w exit headers for thoes newer heads. And im guessing the exost ports are diffrent for the efi to the carbed heads?????

Cody - I know this is an old thread, but did you ever figure out the headers issue? I'm looking at doing EFI on my 76 F250 with 460. Intake and heads are the easy part
