I have a 460 out of a 1995 F-350. It had EFI, I would like to run it "old school" Can I get by, by installing a good dual plane intake manifold with a 4 barrel and an old style distributor?

 

NO. not unless you change out the EFI heads w carb heads OR you can buy an adapter from Price Motorsport to put a carb intake on your efi heads( Price Motorsport ) or put a carb on your efi manifold( Price Motorsport )

 

Price's script doesn't allow for linking anything but the homepage.

Look under carb spacers for item # CS-460EFI or new products for AP-37.

 

Thanks much!!! Dave

 

Sorry for rehashing an old thread but...

I posted over in the engine forum and havent seen a response. I have tthe opertunity to pick up a1994 460 dirt cheap. It would be the base for a high horse street/strip engine. I dont wantnthe efi system and would end up doing aluminum heads any way. Is converting the efi systwm as simple as putting card heads on it or is there something im missing?

 

And intake obviously, but that's about it.

 

Not wanting to open a new thread since one already exists, my 1990 460 is chewing through MAP sensors and has wiring problems. I’m at the point of doing the carb swap as I think I would need to replace all of the wiring and sensors. If I use the Price carb adapter to intake, do I just plug off the injector holes? What wiring can I cut out of the front harness? My front wiring is so sketchy that when it gets wet under the hood, my parking and tail lights turn and won’t turn off until the wiring is dry. I need to find a replacement under hood wiring harness.

 

The price adapters are to put on a CARB intake, not reuse your EFI one

 

Carb Adapters

This states that it will mount a square bore carb to EFI intake.


The CA-460EFI was designed with the performance person in mind.
Put a Square Bore Holley Carburetor on a 460 EFI Intake Manifold or put on a 460 Turbo. This flange allows you to bolt on a variety of choices. The CA-460EFI-HP is for a larger carburetor. The hole size has been enlarged for greater performance.

 

Price does/did make an adapter which allows keeping the stock EFI intake and mounting a carb. I've got two of them on what were previously EFI 460's. Kit comes with the brass plugs for injector holes. Another benefit of adapting an EFI 460 is factory serpentine belt system. And if you prefer a Saginaw P/S pump that pump/bracket can be sourced from an E-series 460.

 

It looks like it come with 14mm brass freeze plugs. I would put a carb intake on it

 

To do that requires a new distributor, intake, fuel regulator, and adapters. $330 for adapters, $365 for an intake, and a taller distributor, not sure how much that is but assume $200 plus fuel regulator (~$150) to knock it down to 3-9 psi. With the carb adapter, its $125 plus regulator (~$150). Is the carb intake worth that significant increase in cost? $1045 versus $275?

 

To me It would be. But I would also be putting aftermarket heads on to go with the carb to get some performance out of all this since you are stepping back 30+ years in technology.
Then no adapters. But thats just me

 

heathdaily was right on with his description of the differences between EFI and carbed engines. There was a transition era from '84 to '86 where an electronic feedback carb was used. It was a rather complicated affair employing four "zones" of operation controlled by three vacuum operated solenoids and about four miles of vacuum tubing connected to all sorts on PVS, SDVs, EGR, AIR, and EVAP devices.

In addition to addressing the different fuel pressure required to change over you must also consider the afore mentioned differences in the rate of spark advance and adjust accordingly. This may require a changeover to a DS II system or similar non EEC controlled ignition.

 

In addition to all else, don't forget about the electronically shifted transmission. Big $$ for an external controller for that E4OD.
