i was in the second hand store down the road from my place when i spied this 4bbrl from across the room in the tool section i was amazed to see a holley 4 bbl plus a 1 in spacer looking in great shape, and the killer was it was 14bucks!!
i took it to the owner, (who i know and trust) asked if he knew the condition and he said his friend got it from a garage he works at that took it off a running customers car to replace it with a edelbrock needless to say for 14$ i snagged it, i found these numbers on it
1850-9 2015 8050b im curious which holley is this? 500, 650, 700cfm? or anything else about it, thanks

thanks i'm not rebuilding yet as i truthfully don't know what im doing with it yet, do these carbs offer a good balance between power and fuel efficiency? i've heard holley can be really fuel hungry, but that's also probably from people who have hi hp screaming motors. i know i should have reearched before buying a carb but was too good a deal, im thinking/hoping it will work on a 77 305v8 but is 600cfm too much for a mild 305?
