Good Morning all. Long story short. I've got a 1993 F350 Crew Cab dully with a worn out motor(320K). Please review my shopping list.

1)Ford 460 Big Block Talladega Crate Engine with 400 horsepower and 470 ft-lbs of torque. Ford Performance Crate Engines
2) Hughes transmission P/N:K46-10XA, Hughes Transmissions Including 35-1 Transmission and 74-1 Transmission
3) JET Ford Module P/N:89309, http://www.4wheelparts.com/Performan...ct&emlprox=out

I called the company about the Talladega Motor, of course he told me it'll work trying to make a sale. I asked him about speed density and he instructed me to take it to a shop that can tune the computer. Which I know is incorrect.

Do I have any Options other than a stock replacement crate motor?

 

Why not just have the stock engine rebuilt? Are you looking for more power? I would have to say that the motor in your list would not work with the speed density. Its probably set up for a carb.

 

Rebuilt stock engine is my first choice. Figured I'd shop around for something better than whats in there now if possible.

 

Thats the thing there really is not much of a after-market for these EFI big blocks unless you wanna do a MAF conversion or just swap the intakes, change the fuel system and go to a carb.

 

I don't see any spec link for that crate motor on the Precision website.
Did the salesman say whether it had Carb or Fuelie heads? (because the exhaust ports don't match either)
I've seen carb adapters or intake spacers for EFI engines to use a carb manifold, but not the other way around. (take a look at the Price Motorsport website)

The built up E40D could likely handle it.

IMO (and I'm no expert on FI 7.5's) you're going to need MAF with a tune, a huge diameter TB and some BIG injectors to support those HP & torque figures.

 

The salesman did say it will work with my 93 EFI truck. At which point I asked him if for sure will work with speed density to double verify. I'm positive he did not know what I was talking about.

I like the Price Motorsport carb manifold. Will it work with the E4OD transmission? I know the tranny is controlled by the ECM. Don't know how the ECM handles shift patterns and such.

I have no interest in a MAF swap.

 

camshaft must be able to produce enough low idle vaccum for the map sensor on the speed density to control air/fuel mixture, so id stick with an original engine and a comp efi cam, i have heard u can trick the e4od by mounting the tps sensor so it moves with the carb linkage as u move step on the throttle, forgot how the guy mounted it but it worked, im looking to replace the e4od with a c6 just for the simplicity and no solenoid pack/electronics to worry about,yeah u lose the overdrive but overhauling that e4od is pretty pricey

 

Well if he did say it will work on your '93 then I would think it has fuelie heads.

The ECM is going to need a Throttle Position Sensor at the very least.
I don't know how to get it to think it has injectors hooked up or what it will do with the O2 sensor input if it is trying to correct something it has no control over.
You certainly don't want the CEL on constantly, nor it stuck in "limp home".
The SD computer does control spark advance as well.

There are some guys on this forum (Conanski comes to mind) who are definitely more knowledgeable than me and may have some input about your attempt.

Sorry, I don't have much else to offer.

 

throttle position sensor (TPS) has a tang on it just a matter of hooking that tang on the carb throttle butterfly shaft, Ecm needs this TPS feedback to control line pressure on the trans also, the ecm also needs the speed sensor hooked up, some of these newer models are on the rear axle, now if u you wanted to keep the efi and adapt a c6, either get a c6 ecm or keep the e40d ecm and trick it by taking out the whole five solenoid pack out of the e4od and just leaving it plugged to the harness, wire tied to the chassis, this is just to keep the e4od ecm from throwing codes (check engine light), also try to get the f3 castings on the heads for the efi they were a little better

 

Thanks Guys for all the helpful information! I'm going to follow mustangman's advice. Order the motor with the Comp EFI cam.

I'd like to keep the E4OD in good working order so I'm not going to bother with the carburetor modifications. It's an over the road hauler. Reliability is important.

My nest questions are: is the Jet computer chip really worth the money? Do I need to purchase a electronic transmission control module for just a fresh motor with cam upgrade?

I'm adding the BBK throttle body to my shopping list.
