The Stovebolt Site Forums The Parking Lot Big Bolts Updraft carb off of coe

I took the carb and manifold off of the 46 chevy Coe that I dismantled. It had a high pressure 235 in it. The carb is a Carter BB-1, would that be the original carb off of the 216 or would it be the original carb for the 235? Dave

Would the carb off of the 216 have a different bolt pattern for the manifold than if it was for a 235?

Any Carter Updraft, from a 1946, or later COE, would have a 235 engine in it. No 2 ton Chevrolet trucks, ever had a 216 in them. Chevrolet's first 2 ton rated trucks appeared in 1946.

But Spanky this is a high pressure 235.

It's got to be a later 235 which were in cars and trucks, I had to file the original manifolds on my 46 COE to get it to bolt on a 1960 235.

The bottom line here is this, I know this manifold came off of a high pressure 235 that was installed in a 46 Coe. I have no intention of using it, if I try to sell it I want to represent it correctly. I do not know much about it. Would the carb to manifold bolt pattern be like the ones on downdraft stovebolt that changed when they went from the 216/235 low pressure engines to the 235/261 high pressure engines. I don't have those dimensions off the top of my head. Dave

I put the manifold from 1946 235 low pressure engine on the 1960 235 high pressure motor. Had to do a little filing for clearance for the mounting bolts

There were four different Carter Updraft carb.s used on Chevrolet COE's from 41- 55.1. 1941 Carter model 489, 42-50 model 517, 51-53 model 871, and 54-551st series model 2045. 41-50 manifold carb., mount the same, 51-55 1st series carb., mount the same. The 54/55.1 Carter 2045, mounts facing forward, because the air cleaner is under the hood.

All I see on the carb I only see BB-1 and D or O. - 456. And today I compared it to a rochester that came off of a high pressure 235 and the Rochester patern is wider. Would this mean it came off of a 216 low pressure engine?

The mounting flange on the 489, and 517 is smaller than the later 871, and 2075 updrafts. So your carb., is probably a Carter 517, which would be from a early 235.

Thanks Spanky. Dave
