The original Holley 780 CFM R3310 model 4150 was and still is a great carb. Out of curiosity, I'd like to see what your base line testing data was and the incremental changes made and their coverall effect. I'm always looking to improve my efforts as I have extensive carb tuning experience and would be helpful to add to my data base.....rather having to reinvent the wheel, do to speak.

Kudos to you. That is exactly what I would ask. Despite not being from Missouri, I'm a show me guy too.
Data, maybe some somewhere. But at some point you need to choose what you want to believe based on the source. I'm fascinated by how there can be a ground swell of miss information that cannot be unravelled.
Generally I don't talk about the road I've traveled in my hot rodding history to get where I'm at today. I'll just hit a few highlights.
Almost all my experience is on street cars. Probably over 1000 track passes with my own stuff, and that pales in comparison to all the street racing I did. Along with that, there was a core group of us, usually 4 or 5 other guys that were doing the the same thing, kinda of a competition to out do each other on a week to week basis. I would change camshafts on Saturday mornings. We tried and traded carburetors all the time. All the: is a Holley better or a Carter, is big better than small, is vacuum better than DP was tested and concluded 40 years ago. But even so, today I've still got about 12 carburetors sitting around here, including a 3310-1 as you know is actually a 780 with the down leg secondary booster and rear metering body.
The stuff I post always comes from real personal experience, or observation paired with experience.
At the risk of sounding arrogant, when I go to the track, most folks that come by are very surprised what my cars run considering what they are.
Take it for what it's worth.
