Hello all fellow Hotrodders!!!

I have a 76 Ford Van/Camper with a 460 ci powerplant. Sat for 2 years and started right up. Customer drove 60 miles, and then EVERYTHING SHUT DOWN AS IF IT RAN OUT OF GAS! Not possible as tank is full. So we have a warm engine shutting down after about 60 miles. The farther my customer drives it, the more often it "stalls out" and wont start back up as if it's not getting fuel at all..ANY IDEAS HERE WILL HELP. We're gonna start by rebuilding or replacing the carburetor. Also, we are going to remove the Liquid propane carburetor, as the customer "doesn't use it" and it's making it so you cannot fit a propper air cleaner assembly to the top of the carb. HELP ME PLEASE......


Okay, I am diving in over my head with my current project. It's a 76 Ford Van/Camper conversion. The person that my customer bought it from has had a 460 ci powerplant put in. (Gotta put an Autozone plug in here...it's where the engine came from and when it runs it's smooth as melted creamy peanut butter!!!) The only problem is that they used the old Ford 2 Barrel carb and didn't switch out the upper intake. ALSO! There is a Liquid Propane carburetor attached seperately that I NEED TO DISCONNECT! Due to the fact that there are no numbers left or "plate" on the Ford/Motorcraft carburetor, I cannot match it to find a rebuild kit. Also, I do not know how I should go about detaching the LP carburetor, as I do not know if it's still attached to the main LP tank!!! YIKES RIGHT! Anyways. If anyone has any idea how I can physically identify a Motorcraft 2 BBL carburetor, without an i.d. plate, please let me know immediately. I am trying to fix this guy right, as he was refered to me by my number one return customer.

Thanks For Your Time

What you are describing sounds like a classic case of the failing Ford ignition box. It runs for a short while until the internals get hot and then shuts off like you turned off the key, and won't restart until the box cools off. The more you drive it the shorter the interval until it shuts off again. Sound familiar??

While some photos would likely help, there's a propane supply line from the tank. AT the tank, there's an ON/OFF valve that needs to be closed before servicing/disconnecting the propane carb.

Prolly a 2100/2150. Is the choke pulloff on the air horn behind the choke tower or on the passenger side behind the choke linkage? That will tell you if it's a 2100 or a 2150. Google is your friend, unless you have a photo or three...

There should be numbers stamped on the base, as well as a cfm rating, would look like, "D6PF-EA". and something like "1.08" on the bowl.

The kits vary, but a kit in the area of these carbs, is Motorcraft kit CT-499D. Cost <$20.

First off, on a '76, unless someone has changed it out, the engine has a point style ignition, which I believe is the last year for that system. Assuming that it still does, give it a tune up with new points, condenser, rotor and probably a coil and a distributor cap. The F250 I had 'way back then' had that problem when it needed a tuneup - and yes, it did have a 460 California smog control gagged engine (for a short while )

I would suggest that eventually the parts be accumulated for at least a late Dura Spark conversion(ignition box and distributor as well as wiring information)

You can find the parts here reasonably: http://www.rockauto.com/catalog/raframecatalog.php

PS - I had a brain wave and probably shouldn't have been so positive above as there were SOME Fords of this vintage with Dura Spark ignition. In two that I owned, car as well as the truck, neither had it.

all my 460's from those years had 4 barrel carb's... I was working for Ford and bought a new one every year at the discount plan.. ,,, the propane conversion might have changed to the 2 barrel. on some they used the sq pattern holly's so it was eash to change the carb to something that worked better.

Holleys or (shudder) a Motorcraft/Autolite. A '74 LTD I owned had one of those gas tank drainers until it went out of warranty.
