[SEL] V-12 jimmy carb question

[Bill Boyce]

a V12 GMC engine followed us home over the weekend,  minus the 2 carbs,,, 
and from what little info i;ve gotten, most of em used  two 2GC rochester 
carbs,,,after checking around town and not having ANY luck finding one ( 
seems the dirt track guys have gleaned em all up ), i logged onto Ebay and 
found several listings,, i did have one stuck in the back cabinet of the 
shop, but have no idea what it came on,,, the carbs on Ebay are listed as 
"small bore" or "large bore" , so here is my question: does anyone know what 
the bore size is for large or small bore ? if i knew, i could measure the 
one carb i have and then match the one i buy to the same bore diameter,,,,,
i could use a more common carb like a 2 barrel holly or motorcraft, but 
would have to use
flange adapters, as the 2G's have smaller bolt patterns,,, or, a couple of 
propane mixers would really make it simple,,,, but a couple of gasoline 
carbs sitting in the middle of 12 zoomies would sure look neater,,,
