What is the cfm rating for these carbs? This is a neat swap.

When comparing CFM ratings, keep in mind that IR systems are apples and oranges to a regular carb on a manifold. With sidedraft Webers, you might calculate over 1000CFM in total airflow for a 200 ci engine.
The other thing is that those are Constant Velocity (CV) carbs, so the opening corresponds to the airflow. It's harder to over carburate with CV's.
that's a new video (2nd one) from last time I saw that guy running the setup...
that is what I would love to try, good to see a video of the work that has been done to the logg!

Like the head mods, IMOP think would be better to use 3 Weber Side drafts.
it's possible but IIRC the webers would fit with more modification, I like how simple he made it with 2 sets of 4 carbs and took teh outer carbs off and the spacing lookes just about right...bubba22349":1tbabcd9 said:
now jetting those carbs would be a pita... x6 but I'm sure it will make much mroe HP than any of our 3x1 or 2bbl setups... might be close to a good 180 RWHP if it was a different cam...

Since a "CV" carb used on a Harley supports roughly 80ci, you would think 3 would be sufficient on 200.
