47-55.1 216 to 235 swap - carb. fitment problems?

[Moeller]

Hi All,

I just put in my newly rebuild 235 in my 1953 truck, and wanted to put on the carb (stock Rochester B) from the old 216 that I took out of the truck. Then I found out (google was my friend) that the trottle hounsing on the 216 is narrower between the bolt holes than the trottle housing the 235 stock intake I have.

So, my question is:
Besides from the trottle housing, is the rest of the Rochester B the same on the 216 and 235?

In ohter words, do I need to find a complete ohter carb, or can I just change the trottle housing to the size that fits the 216 intake?

Thanks,

Martin

You need to get the 235 carb. Ive seen ones that a guy cuts a slot in one of the mounting holes & used it that way but you will be loosing performance. The size of the throat is different. Same goes for the intake manifolds.

Yes, but do need to get a complete carb? - or can I just change the lower part (trottle housing)?

I'm not sure but I believe the throat in the fuel bowl is smaller too.

Ok, I guess its best to look for a complete 235 carb. Thanks!
