I have what are supposed to be 825 CFM Barry Grant Demon Marine carbs. I would like to verify this, but there isn't a single number stamped into these things anywhere! Anyone know how to determine a BG carb? They both ran great (one at a time) on my 520HP 454 on the dyno which only used 680 CFM @ 6200 RPM. So since they ran so well, I am wondering if they really are 825's...



Thanks!

HAve you been on the demon site? There has to be numbers on them. Can you post a picture? I am running the Mighty Demon Marine 850's on my pair.
