I'm in the same boat as yourself. I've looked at the Langdon's Stovebolt site and they have a 2 or 3 carb setup manifold. But if you want a 2bbl setup, you'll have to get the adapter part from their site as well.
I plan to upgrade to a Offy 2 x 1 intake manifold with the adapter plates to allow 2bbl carbs. As for the carb I'm still researching. I have the chevy inline 6 power manual book from Leo Santucci and has given me loads of info. . .but I am still unsure on the carb. I want 2 2bbl carbs rated around 300 to 350cfm. From the book that seems to be an ideal setup for street/strip. Although she won't be seeing any strip use for a very long time.
I've also thought about keeping the manifold as it is and get the adapter kit and have 1 2bbl carb at 300cfm.
But the book gives you alot of ideas on what you'll need to do.
Companies that offers the manifolds are:
Offenhauser, Precision Engine SErvice, GMC, and Clifford.
Headers. . .good luck. So far Langdon's Stovebolt has the only thing that I see would work for me.
Good luck man!!
