I have a rebuilt 200 six that I just installed into a 64 falcon which originally had a 170. My problem is that the cylinder head on this engine has the larger bore than the 170/200 normally has. The casting code says D8OE. The block is a C5OE. Is this a 250 cylinder head? If so what are my carburetor & throttle linkage options? I have a spacer plate that fits but no where to bolt on the swivel for the linkage. I have a carburetor for it that looks like a larger autolite 1100 with the linkage in the same spot as the smaller carb. If I could get the stock swivel to mount up this all could possibly work. Is there some kind of adapter for this? I’m mainly a V8 guy so this is all new to me.
