I snagged a carb off of a 68 out of the junkyard. The linkage was a cable that someone adapted to the original gas pedal. Thusly by passing the funky 3 link setup.

The carb has a nipple on the side for a snap on linkage.

So....the cable is too short The gas pedal is about 5 inches off the floor.

What's the experts say in regards to adapting. I am thinking of building a loop of wire on the end of the gas pedal at the firewall. That would allow me to lower the gas pedal in the cab.

I guess maybe going back to the original truck and pull that gas pedal...
which was probably adapted to work by that owner.

 

You can also do like Ford did and eliminate the trapeze with a straight section of rod.

 

Yeah, that trapeze is an oddball thing. I think tomorrow I might measure it out, where the pedal should be sitting at idle then go fabricate me a rod.

I viewed some stuff on this site what others have done and on Google....so I think I can do this

 

The linkage on the carb is called a ball stud. IIRC, the 77 and later F-series used 'em. It's an EZ swap.

Lokar has a nicely engineered throttle cable system. I figure it's EZ enough to replicate using..... bicycle brake cable and hardware.

 

FIXED! Wondered Pik n Pull this morning with my bucket of tools and a red wagon. I found a 67 that someone had earlier swapped the trapeze funky step up over. I pulled it.

Then I found a 77 F350 with the correct unit. Pulled it.

$28.00 plus entry fee. Swapped it over on my 71 F250, got a nice idle out of this carb. Then pulled the 6 blade flex fan off. I at some point in life bought a plastic 6 blade fan that weighs about 4 ounces.

My 360 has a nice 3 core radiator that is almost new that I snagged last summer with the shrouding.

I was seriously going to sell this old girl. But now I think considering all the work that has gone into her, and all she really needs at this point is new bushings on the twin-I-beams and maybe king pins, I'll keep her.

Oh I pulled a Motorcraft 4b carb that looks like it was made by Holly this morning too. Came off of a E250 probably about a 1988 model. Not sure why, but it was cheap. So it sits on the shelf with the rest of the 2100's and 2150 for eternity.

 

The "made by Holley for Motorcraft" carb is a 4180 Holley. It is the best Holley out there for fuel economy. Well, at least the best that 460 can do.. This is because Ford made Holley put in them Annular Discharge Booster Venturis on the primary (front) 2 barrels. Like Ford did in their carbs in the EARLY 60's. These atomize the air and fuel better. They were built pretty thin (AKA lean) though. #61 jets,.028 accel pump nozzles,purple secondary spring. At the moment I don't remember which secondary metering plate was used but it was thin also.

 

Somehow I now have two of them. I guess I might want to look at a 390 4b intake and try one.

Or sell them on Ebay.

390's love fuel. You ought to jump to 64 jets. With headers and high flow exhaust it might take 66's. I'd try the 64's 1st and read the 390's plugs. .028 nozzles might go well with the 66 jets but it'll prolly want .031 nozzles with the 64 jets. When I get home I'll look up which secondary metering plate it came with.
Note, On the front of the airhorn it will have both the Holley list number and the Ford Motorcraft "tag" number. There are a couple 4180 specific gaskets in it. As of 1985 ,I believe, they went to a big housing diaphragm style choke pull off also.
