help with carburetor.
I am asking in this forum for a friend. Problem is on a big truck 1956 or so.
Has a big Y block and 4 speed, kind of an F-6 or 7. The carburetor on this engine is an odd ball 2 barrel that parts are basically hard to find. The engine it self is like a 292/312 but the manifold where the carburetor bolts up is much different in size than the standard old 2 barrels.
I want to put a later 2 barrel on it just to get it running but the bases are different. I was told that the odd ball base was similar to some other carburetors out there like Rochester or ???
Anyone know what would be a good cross over for this thing?
thanks.

Pictures would help also. Some older carbs on big trucks had governors that made them look weird. I'm not familiar with the details or how that would impact the mounting as I think some mounted between the carb and the manifold.

Does it have the "teapot" carburetor? It may also have the load-o-matic type distributor, vacuum only does not include mechanical advance. They work together, and usually not very well. Best to replace the distributor as well if this is the case.

photos etc..
Here are a couple of photos, the smaller blackish plate is the size of the 2 barrel that was on this engine, the larger base is a standard Ford carb off of a 352. Notice the difference.

The small base carb looks to have the same pattern as "small" base Rochester 2G's used from '55 - '64 or so on GM products, but would have to have actual measurements of the bolt pattern to confirm. They are great carbs but will not support a L-o-M distributor.

carb and distributor
All we need is a carburetor to get it running half way decently again so that they can get it sold. We had it running for a while but the old carb finally gave up the ghost. The engine is strong and it and the truck might be of interest to someone out there but running is better than not.

When I was 14 we moved to a new town 3000 miles away. My new best friend was named Hermon. His dad had a 5 man shop building custom fire engines for neighboring towns and even Logan Airport. Bear with me here... Hermon's dad found him an aluminum bodied Rover sedan for his first car at 16. It cost them 60 bucks and they towed it home with one wheel locked up. You could follow the skid for 3 miles. Turns out it needed a carb. 1959 rover not in the napa book. (or Hermon senior's). Next day it ran perfectly with the carb off their 6 cyl 63 rambler wagon that had given it up a few months earlier. Dad had taken a short piece of 2" pipe, welded on a 3 bolt flange and a 4 bolt flange that matched the specs and off they went. For six or seven years! I was floored and I never forgot it. That 'high class' British rover engine didn't give a rat's a** what or who was atomizing the fuel it sucked in. Ok all this to say find something that sort of fits, cobble up a linkage and sell it. If someone here finds you a good replacement, just ignore this post. I tend to ramble......

You mention "big Y block" it might be that it is a Lincoln derived Y block? They were used in the big trucks as well as Lincolns starting in 1952. 1952 Lincoln's had a two barrel carb. Holley 1901 that looks like a similar bolt pattern. Re-build kits and adapters are available that might work for you.

1956 F700/900 would have either the 302 or 332 Lincoln derived Y block.
302 2V = B6Q-9510-A 2V Holley Carburetor; B6TZ-9A586-A .. Carb Tune Up Kit / B6Q-9590-A .. Carb Major Overhaul Kit (1 available NOS).

Requested photos of carb base
Here are some photos of the phenolic base plate of the old carb with tape. Basically I need to find another carb that will fit this with the throttle hook up on the (driver's side). This would only be temporary to get the engine running again so my friend can get this truck sold.
