580 cid BBC, 15:1, single carb setup, 430 cfm heads, 7500 RPM traps, 3 speed, 5000 stall, transbrake, possible switch to Q16 after trying C14/X16. 900 HP level.

What CFM 1350 1450? Or 2 circuit or 3 circuit? Car is driven from pit to staging lane and back after race to pit, so power valve or not? Economy is consideration if possible. If I missed any other factor, please ask. Thanks in advance.
