Since my name has been invoked on this (BTW, I don't know about being a Jedi Master, I'm not that old but have been called Lord of the Blue Oval). The 4180C has an electric choke that is designed to operate on the 7 volt stator output of a Ford alternator. On some 351 applications, probably light duty 4 barrel use, there is a elaborate system with a relay to shoot it with 12V under certain conditions (emission related I am sure). Holley sells a 12V electric choke, but it is a little hyperactive for most applications, coming off in a hurry and coming back on after only a short cooling period.
Thank you, oh masterful (and ancient) one! So, the choke heater from a 4180C should work well on a 2150 to eliminate the hot-air choke. Or, at least as well as all-electric can. Right?
Provided that (A) it physically fits and (B) that it works in the same direction.
I have my 0-80457 fitted with the Motorcraft 7V choke that came stock on my old 4180.
In other threads I have heard of putting the 12V choke element on a 4180, but you lose the 'only active while engine turning' feature.
It is polarity sensitive and needs a ground attached to the second tab.
If I can find a pre made reproduction choke tube for this truck I can find a proper size drill bit and attempt to drill the manifold out without removal. Thing is though as I said mine only had one tube no tube coming up from the manifold. I think it just sucks hot exhaust gasses.
Earlier 385 series engines had a coiled tube that fit into the exhaust crossover in the intake manifold.
Dorman/HELP made a pre-bent coil to fit this.
I don't see it on the shelves anymore but I bet you could get one.

I've added a new page on my web site: Carburetors & Chokes - Gary's Garagemahal. How 'bout looking to see if you agree. I'm hoping to document the discussion we've had on chokes, and thought discussing what carbs were used would help as well. What's wrong and what is missing?
Very good sir, it is reasonably correct for the 300, 302 and 351W engines. 351M, 400 and 460 engines had the aforementioned coiled stainless steel tube in the crossover. The later 460s still had blockoff plates there (red circled area).
