1996 351W ?

[Brandon]

Hi. I have found a 96 351W roller motor. My question is that I would want to go carburated for my car. I know the 96 is fuel injection. Is it possible that I can take a manual fuel pump timing cover and put on it and it would work? Or would I have to go buy differnet parts for it?

I don't know the specifics of what came on what years, but you'll probably be swapping to an entirely different timing cover anyway. All you need specifically for the mechanical fuel pump is an eccentric on the camshaft and a timing cover with fuel pump mounting provisions. My first carb conversion used my stock '87 Colony Park timing cover, which had the mounting provisions but wasn't drilled out, so I was able to reuse that cover after a little work with a drill and some big files. If you'll be yanking a stock Vic motor (5.0 or 5.8, doesn't matter), and that timing cover has the fuel pump mounting bosses, you're set as long as you also have an eccentric handy.

Yes you will just need a different timing cover as far as i know. The truck water pump is a little different, though.

Or

You can spring for a cheap aftermarket electric fuel pump setup for carburetor fuel pressures and leave it.

If you're going to swap to carb, I'm with Outlaw- just run a budget electric fuel pump and get an in-tank pick-up from an older carbed Panther.

What's your reasoning for going carb, though? Keep that sucker EFI!

Timing cover and the cam eccentric, or go electric. Your option. Out of sheer laziness, I'd go electric, or more realistically I'd convert the thing to EFI since I'm not much good with carbs.

I am pretty good with carbs, but if you live in a high-altitude area like I do, and occasionally drive to lower altitudes, I'd keep it EFI if possible.

Another issue is whether or not your state requires you to run garbage ethanol-laced gasoline; having two float bowls full of fuel that turns to vapor in a hurry is not my idea of fun, especially when you have to try to start the vehicle again in a few hours.

I like the idea of keeping it FI. That'd be unique as hell. IIRC, the late EFI 351's don't really look like anything else Ford made when they're under the hood, so you'd be able to stump quite a few people.

If it's easier and/or legal for you to go carb, than by all means do it. The only other mang here to keep the 351W EFI is Heretic. He might be able to answer any questions you might have if you should keep your 5.8L EFI. I would have done the swap myself by now, but funds are lacking. It will be done one day.

Actually, what would one do about the TB cable on a 351W EFI swap? Reuse the 5.0L TB cable?

Packman, why wouldn't you reuse the 5.0 TB cable? The TB would be in the same place.
With a properly functioning HO conversion, there is a minimal difference going to a 351 except you'll have 49 more cubic inches to help produce torque.

...and you may need to have the hood raised.

Is Heretic still active here? Is there a build thread on his EFI 351?

[packman]

Nah not yet. He's not finished.

As far as the TB cable, I wouldn't know because I haven't even done an HO conversion yet. When I do an engine upgrade, I'm going to just jump in head first and go 351W. If the 5.0L TB cable and bracket can be modded and reused, then all the better.

rumor has it from heretic is that the hood closes if you use the lightning intake and no spacer

It makes sense. I had a 1" spacer on my GT40P in my old wagon and the hood closed with plenty of room.

Brandon- it just occurred to me that you have a P72. Is that a 351 already? If you're already on a carbureted car, by all means- keep the carb. Much easier that way. I was thinking you were ditching EFI from a 302 for a carb.
