I put super 6 complete set up on my 1966 Plymouth Valiant stock 225 with 3.23 gears This winter doing the head. What’s the best adapter for for Holley 2300 350cfm carburetor and what jets do I need to start with..Thanks

I have one in the garage, I will look at it and post the info tomorrow.

I have 2 types, an Offy and a chinese one that I got from Summit I think.
The chinese one is a lower profile.
You would need to check what direction your linkage is going to run and see which one works better.

There is a guy on ebay that sells a nice adapter. His primary market is Jeeps with inline AMC engines. But they used BBD's too. So it would be buy and bolt on.
