I have a Carter 6212s marine carburetor, its numbers indicate that its for an early 70's 340 marine engine. I would like to know if anyone could tell me what cfm this carb is? Also, if this will work on a car. Thanks

Off the bat I'd say that as per the old Carter tech line, the OE carbs were rated at 630 AVS/AFB's.
Though, now that I see the ruler, I'm second guessing myself. I can't remember the butterfly sizes at this moment.

It'll work on a car. No problem.
 
Marine carbs have no vacuum advance port for the distributor. It looks like a 650 cfm.
