I'm aware of the transfer slot/bypass hole size/cam/compression ratio, etc. relationship. What I'm trying to accomplish is to get the carbs back to somewhere close to the original baseline as far as the holes in the throttle plates are concerned. I imagine the holes in my outboard carb throttle plates have been opened up, I was wondering how much.

Did those #199 throttle plates come from Holley with a bypass hole drilled? Do you know what size they were? Mine have the #226 plates installed so I'll probably replace them while the carbs are apart.

The 199 plates had no holes. I drilled them 5/64" (0.078") on an angle
