Gentlemen;
The 216/235/261 manifolds are the same basic l930s technology, which were made to utilize that type of carbuertor(s)world wide, back then.
Today; We all have a variety of manifolds, carbs & EFI devices to consider, relative to our needs/climate/geography and altitude etc.
This alone, should be the guiding factor(s) in creating anything and not what someone else did.
I would ask the Webmaster how to post photos and always remember the basic rule of auto mechanics.
"If It's not broke, don't fix it".
