"94" Fuel inejcted 460 Aluminum heads

We have a "94" 460 F350. If we stroke and engine will the computer work or can it be tuned to work with a storke change? Would an aluminum Head transplaant make as much power with less Computer problems? Do I need a different block to go to a Roller Cam. Where would a guy find out what the codes stamped on the blocks. I've read an article that stated the 88 to 92 block is the strongest will it handle a roller cam or it this a true statement. There are alot of informative People in this group So I think I'm comming to the Best place for this info. We haven't call hot rod shops yet Mainly because they don't drive wht we do and maybe some of have what we want to try out. Expreince is the best teacher.

I believe all of the 79 on up blocks are the same. 88-92 heads have smaller valves then the 93-97. Any of the mods that you are doing, you are going to have to convert to Mass air, which can be done but with a price.

The only aluminum heads available are all out competion heads or Cobra Jet's . Will the 94 fuel injection manifold bolt to the CJ's?

No. FI heads have a different intake angle.

The EFI heads will bolt to the earlier heads. The ports do not match up though. If you port match them it works. I have 1970 D0VE heads on my 1992 460 running a mass air computer.

It is not easy to do, but it can be done.

John were did you get the mass air set-up, and was it worth the work to change to the earlier heads. Thanks

The mass air setup is the origianl 1994 Bronco 302HO engine control system. I have a programable ECM "chip" to change the displacement from 302 to 460, change the injector firing order, and some other mods to make it run well.

If I did it again I would use the 1997 Calif F350 7.5L mass air ECM instead. Without the chip.

I can get a set of 429 heads off of a "70's" LTD with rocker arms studs will these have the right angle? Can you pass polution check points with your engine? I would like to get as much torque are I can with out making as many head aches as owning a diesel.

The 1970 heads will not help you pass emmissions. I cannot tell you for sure as we have no sniff tests here. There is a huge amount of work to get the heads to match to the intake. You need to grind/port the top of the ports in the heads and the bottom of the ports in the intake. You will need to make your own gaskets. I built up the aluminum on the bottom of the intake to provide better gasket sealing. The stock PCM will probably not like the modifications as well.

It is interesting as a hobby project but I would be hard pressed to call it a practical modification.

I did the maf/460 conversion. I ran the extra injector wires(ecm pins 12,13,14,15,42,52 to run inj 3,4,5,6,7,8) It ran ok. I realized I had a new firing order on the A9L ecm and moved pins 12&42 for 13&14 to "correct" the firing order. I think after dealing with batch-fire, the out of time squirts were barely felt in the new setup. I provided a set of single connectors in my injector harness to "move" these runs to correct pins. Tuning is my biggest issue and I wish to hear some input on this. I use a maf-tuner(pro-m style) and what works good one moment is out of style the next. I constantly am correcting the hi and low speed ***** from "450" up to "570" settings(bearing in mind that "500" is straight maf signal-to-ecm). 76mm MAF tube design may be a problem??? I use a C&L sample tube for 76mm/30lb and a set of TBird 30# injectors. My choice of 30# injectors was based on 460 cu.in. as opposed to 302 and its 19#nozzles, trying to keep pulse width needs in line. ----A lot said here, hoping for a lot of answers.BT

bt,

I am currently running the stock 302 PCM (HOGO) with a TwEECer to change some computer settings. I have changed the displacement, a couple functions that tell the engine how much air flow is required to keep a given idle speed. I also made some changes to fix trouble codes.

This setup is only good up about 3500RPM before the MAF and injectors reach their limits. I have #30 injectors as well and I plan to get the Ford 90mm MAF that comes on the 1997 F350 7.5L MAF implementation.

email me at notgnihtrow(No Email Addresses In Posts!) if you want to talk further. I would be interested in some more details on your implementation.

When you upgrade from speed/density to MAF, are some of the parts retrofit from a newer Ford or are all of the parts custom?

I'm guessing computer and MAF from a newer model and custom wiring? Is there much else that gets changed?

Google turned up Ron Morris, is this on the right track?

I have tried to stay with newer Ford parts. I'm going for dependability and low cost, not most power.

I have not used the Morris site. It seems heavily Mustang oriented and light on the truck stuff.

I amlooking into driveability first and power next. I look to stock stuff and am trying to size the injectors and maf so I can later boost it and still have fuel on hand in proper amounts. The idea that the 460 is 50% more than a 302 led me to the 30# nozzles that are 50% or so more than 19's. I hoped that the pre-written part of the ecm would have been right for that??? I am pulling tha bat.cable and letting KAM go down for a night and also Fluke meter checking the O2S's again(pins 29-gnd and pin 43-gnd) If I remember right the 4th wire on a HEGO goes to the block, so it is like a 3-wire HEGO. Just WHICH wire? The various books contradict here at times...

Stock 460 Injectors are 24# at 40psi. Upping the fuel pressure may be all you need.
