the truck is really gutless because it should be able to at least make the tires spin when you take off hard with the truck empty, not even a squeak out of the tires. pulling a 16 foot flat bed tandom axle goose neck trailer empty you really have to mash the throttle down to go up a slight incline going down the freeway. I read in one of the responses about the cat. being plugged?? how can I check this? cut it off and use a "test pipe" The truck had a new trans put in it several years ago but only about 20,000 mi ago. to me it shifts too fast into OD and takes alot of throttle to shift down. Is a normal of this trans? What are some mods I can do to this truck bring up the power without a huge bundle of cash.

 

I did the same thing when I first built the 429, I put it in a 79 f-150 4x4 the motor blew the rest of the drivetrain to pieces( 3 trannies, 2 rearends) the I put it in a 84 f-250 and that only ate a ring gear.

 

429's never came in pickups, that I know of.
(pickups didn't get Lima engines until after 429 production ceased for passenger cars)

Now, there are plenty of long snout 429's (both gas and propane) in larger trucks like F700's.
But then you have to turn the crank and mess with a whole bunch of stuff to make them work.

The Man knows his stuff!

 

Headers and a single 3" exhaust would help.
4X4 and a side tank make true duals pointless.

MAF trucks were '96-7 Cali only.
Conversions are expensive.

I have a gearbox, but Baumann makes an OptiShift controller+ harness
And Transgo has 1/2" valve bodies, these are not as expensive.
Beyond that I don't know much about E4OD's

I searched up this thread... https://www.ford-trucks.com/forums/7...ft-module.html

 

It just occurred to me... have you checked your fuel pressure?

I find it hard to believe an unladen 460 P/U can't break the tires loose.

 

checked fuel pressure and it is about 30 psi at idle.

 

What happens if you disconnect the vacuum line?

 

which vacuum line are you talking about?

 

The one going to the FPR....
Is there fuel inside the vacuum line?
What pressure do you see with it disconnected?

 

where is the FPR ? I have not worked on this truck a lot

 

The fpr is on the drivers side fuel rail just to the right of the distributor next the the fuel rail connections. It has a vacuum line on the top that connects to the center vacuum port in the lower intake manifold.

 

I have removed the vacuum line and I did not see any wetness or fuel and when I removed the line my pressure went up to 40 psi. What is tis supposed to mean??

 

That it is functioning correctly.

 

I agree with Nevada Al, if your that close to Scotty J he is your answer. That dude can help you out. If your serious about making it run do what he tells you. I told him I wanted mine to pull like a freight train, did what he said and it pulls like a freight train. It even got an average of 1.3mpg improvement while doing this.
