I have an Offenhauser 1078 4bbl manifold but it's at the engine builder and I can't measure it. I have read about every thread/post about these manifolds and carb. options but saw no specifications. I have considered another Offenhauser 1078 for another flathead that I have and was curious how the WCFB throttle bore and the 1078 compared. I have a perspective source for early Carters used on early '50s Buicks and Olds.
Happy Holidays,
