Slant 6 4bbl Carb Selection

This is what I originally wanted, but no one has the manifold in stock or will any time soon. I have been in contact with a guy in a warehouse in Australia and he was in contact with the manufacturer who said they broke their mold and have been since unable to resume production.
Bro, as someone who spent multiple years in the motorcycle world, trust me when I say you do not want a multiple carburetor set up. You will need to buy tools(no big deal) and learn how to properly use them(big deal) to get the carbs synced. Once you have the knowledge and tools it can be fun, but until then it can be one big exercise in futility.

I’d buy the Avs2 and the tuning kit and just run it out of the box. Once you master tuning a Carter/Edelbrock carb, then I would look into adding another carb.
