Asking, not arguing. Would you have went with one of the slower carbs? I have 1200 CFM's right now on a basically stock 318 with home ported heads, summit cam. stock converter and 2.76 gears. Performs excellent! And yes, I know it isn't using all 1200 cfm's... LOL. Truth is, No carb flows any more than what the engine will take. So, if his 340 will only flow 595 cfm's, guess what, that 3310 is now a 595 cfm carb. :)
