My friend just did this on his 68 with no issues, so I'd say you would be fine., since both are square bore carburetors. This really seems like a great carburetor and I like the idea of annular boosters. His car seem to run better than it ever has before and also has greatly reduced tailpipe odor. After seeing his first hand experience with that carburetor and reading some posts here about it, I have been tempted to do the same thing and swap out my 1806 with the SUM-M08600VS.
