Did they use the dual carb manifold from 1941 1942 Buicks? We like photo's 70 years on the carb's could be anything now. Several threads with good content on dual carb straight eight Buicks Link to comment Share on other sites More sharing options...

Oldxr Posted May 16, 2020 Author Share Posted May 16, 2020 Carbs are Stromberg 2 barrels. Haven’t really check the carbs for #. Thinking of just getting a wide band o2 meter and fixing it . California gas burns lean and a wide band will get accurate results . Problem is I have to weld an o2 bung on the exhaust . Then throw on a 12v battery to run it temporarily .

critterpainter Posted May 16, 2020 Share Posted May 16, 2020 NOT the orig rear carb at the least. Originally the engine ran off the front carb and #2 came in under high vacuum. Only the ront carb had a choke and accelerator pump. Link to comment Share on other sites More sharing options...
