Wow, I always thought the Mark VIII block was cast iron.
Maybe I'm thinking of the Navigator's 5.4 4-valver?

'74 F250 Highboy FE390 deceased! I've been wrong before, I'll be wrong again. Just wait and see.
Sure thing. Thanks for the info. The last message I sent about it was a PM.
Stupid Questions: 79 guy, You have power steering, right? I was just wondering, as you said there is little room around the steering gear.
What's the idea for the Drive shaft? (custom, or a particular length?)
Are you gonna stick with the 9 inch Rear? What gears do you think? The Lincoln had around 3.77, right (from memory, sorry if it's wrong)
What are you gonna do about the Cluster? (Speedo, guages)
Will the lack of systems common on the Lincoln make the computer go loopy? (Lincoln has power everything, air ride system, climate, safety airbags, etc; I want to use the factory computer to save $, but run my old school '74 heater box, old school exterior lighting, etc )
yes i have power steering but that clears fine. it is tight around the steering box and header, becouse the sterring box is on the drivers frame rail rite by the new location of the header.
as for a drive shaft you will need a custom one made becouse it is shorter, your truck should have a split two peice one like mine anyway so have a one peice one made, it wont cost you as much power that way.
i'm stikin with my 9" rear and adding 430:1 gears, i did the math and asked a few guys with stangs. with the 4.6 high rever and a 4speed auto and no imrc plates you need at least 430's to keep the rpm's up so it makes power.
as for the cluster, i am using my factory one and wiring it up to work with the 4.6 sencers.
as for wiring, save yourself the heartach and spend the $900.00 on the custom sonvertion harness, i have spent a ton of time trying to master the lincoln harness, but hay it has not started yet. though i am sure it will run on my system, it was a pain in the ass to play with and i needed ewvery harness from the car, then i had to weed out all the stuff i didnt need and once it is done, i will need to spend 700.00 on a custom tune so the engine runs rite with all the lincoln stuff missing. thanks
The price difference from the Mark vs. cobra engine is the heads. The cobra has a FAR superior head design. They are both teksid blocks.
from what i gatherd the headds are the same from a 93-up mark viii as 96-98 cobra heads. they are both "B" style heads, it was not till 99 that the cobra got the better flowing "C" heads. however the cams are diferant, please correct me if you are sure i'm wrong. but thats what i have read and heard. thanks
ya i got ya, thats the same way i felt. i could have built a gas sucking, always under the hood tunning it 450hp 460 or i figured i could make better mpg's run cleaner and not need to constantly play with it and still have a good solid 350-375hp and just run my 4.6.. i was told the 302's in these years only make about 100hp at the tires.. so big improvment adding the 4.6!!
one other thing for ya,
you will need a power steering pump from an early 90's crown victoria "one with a steering box yet". becouse the rack and pinion pump from the mark viii wont work with a steering box..
Have you done any research on whether the Lincoln motor will run with a Mustang Manual Trans?
I usually drive mtx, and I've done atx-mtx swaps on Jap cars before, rigged wiring and swapped whole harnesses. That's what pulled me in. I'm a fiend for cams, the more, the merrier.
This was going to be my simple toy, but the facts of high gas prices, and low MPG for mediocre HP got me moving in this direction. My original idea was to sell a few old engines and trans' to get the cash to go Efi, then I started down this path. I do want to see you successful before I begin though. Wiring isn't usually a problem for me.
I'd say ground faults, or ATx safety switches are probably your problem. You need to test grounds with a voltage tester, not just continuity. A partial ground won't do with a computer. I'd run the harness as though your truck was a Mark VIII. Use the ignition switch, use the cluster (for now), heck, rig up the darn crash sensors, everything you can. Most of the time tuners run without nearly everything though. How did you set up the Fuel injection? Is the Fuel Pump in the tank? It usually is on all the Jap cars I've worked on.
How far are you?
1. Do you get it to crank when you turn the key? 2. Are you getting fuel? (listen for the Fuel Pump whir, or pull the line off the Fuel filter to check for pressure, it should spray out, watch your eyes) 3. Are you getting spark? (Crank the motor and spray Carb Starter in the intake. If you get ignition, you got spark) Heck, you can get a pin-out diagram of the ECU and a tester and check the grounds, you can use jumper wires to run the FP to test it, things like that.
That's all there is to Fixing a Jap style motor (tuner). Old school guys tell me it's hard, I say they're impatient.
Do you happen to have a digital copy of the Mark VIII shop manual? If you do, I'd like a copy, so I can better picture everything in my head.
I really would like to run an MTX. No muss, no fuss. Heck, I haven't driven an automatic on the highway in 10 years.
I hope I can help, I'm not a licensed mechanic, just a college drop-out mechanical designer.
Finally got a chance to catch up. Just got back from the hospital. Needed a knee. My projects are on hold. Happy B'day dude. I just had me one but a long way from 18. Sounds like you are progressing well. Good luck.
ok, i still have not mounted the cab, after thinking it over i decided i'll slow down a bit and make a smooth firewall for it first. reason being is the cab i got is an a/c cab so it has a huge whole in it. i was gonna just bolt a plate in over it but a think it makes more sence to take it ove tomy buddy's shop and have him weld in a flat smooth firwall out of heavier gauge steel and then rather than paint the ening bay black i'll paint itto match the truck.. wich will be paint "dove gray" i decided, it's kinda like a shiny primer color.
the way i look at it is if i'm spending the money to build it and want it done the best way i know how, then i better just take my time and do it rite.. "BUT YA NEVER KNOW WITH ME, I COULD CHANGE MY MIND AND MOUNT IT TONIGHT"....LOL
I've got the same hole in my firewall. I'm gonna put in a plate, and mount my '74 heater box. It's simple, two operating cables. You need defrost around here.
