Dan,
I do not want to hijack the thread, but here are a few more comments. The center carb on a '66 is higher than the end carbs, but the throttle plates are the same as the end carbs. Venturi is a little smaller for the stock center carb than the end carbs.

Baron, Your info is correct, and 350 cfm per carb sounds reasonable. But, the flow rate of the '66 Tripower setup is usually stated to be 750-800 cfm. That would put the individual carb flow rates at 250+ cfm. It's interesting to note that the modified Rochester 2bbl. carbs commonly used for circle track racing are described as 500 cfm.

I have purchased several restorable '66 Tripowers for $900-$1100 on ebay. By the time you color the carbs & plate linkage parts, get rebuild kits, buy fuel lines, PVC fitting, choke parts, and air cleaners, you will be at about $2000. Coloring the carbs is getting to be more expensive at a rapid rate. I have had several sets that someone painted the carbs. This makes restoration even more difficult.
