390 fe carb question.
What is the stock cfm on: 2bb stock 390 standard
4bb stock 390 standard
Do you guys thnk that a 600cfm man choke is saficient or is a 750 a better choice. I only want speed/HP and the ever popular tq. .... I plan to use my stock 4bb cast iorn intake, maybe port it and magnafulx it too.
Any sug. would be nice...

Justin, I think a common mistake made by guys is that the bigger the carb the bigger the performance. Your truck came with a two barrel. A 600 cfm should dump all the gas that the engine needs. IMHO
