holley 2300, what cfm???

hi! I just got a new holley 2300 off ebay for my 4.3l chevy. It is new but it didnt come with anything and there was no info so i was wondering if someone could somehow find out how many cfm this thing is. on the bottom underside it has a 5.05 stamp, on the back of the riser on top left it says saej - 1223, the right says 3863240, 75028-1, 0833 and if you were looking straight down from the top it has 6 r 3250 b and 38 underscored. it is a marine carb if that helps. thanks

thanks, i think it is a 350 cfm which I think would be fine for a stock 4.3l v6, huh? but how do you know its the 350 not the 500? thanks. sorry I don't know much about carburetors.

not too bad for $80, and I'm pretty sure the 650 that came off the other motor would be a bit much.
