[my70superbee440]

iv got a 70 superbee with a 440 in it and it seems to be running ok but dont have much power feels doggy no take off or topend it has a 600cfm edlebrock on it iv been told its to small but seems to be running rich but you know how it gos if you cant trust the 19 year old kid at autozone thats drives a civic to tell you what your big block mopar needs who can you trust iv had the car sense i was 15 had 5 or 6 carbs on it 750dp holly and it still ran like a farm tractor timimg off maybe ??? or am i just asking to much from a 38 year old motor ????

Probably running rich due to a lack of air. It's choking itself.

Even a 600 cfm carb should run OK on a 440,except on the top end,where it will definately run out of air!. There are many variables here!. Is the compression good? Does it have good ignition? Vaccum leaks? Weak valvesprings? Timming and advance curve set up properly? I would say after 38 yrs it may be time to address everything!. First thing i would do,is to switch the carb to at LEAST a 750 cfm rating!

It sounds like the car is shot. Ill take it off your hands so that you have more room in the garage. Youll have to pay me to haul it away for you though....

I agree, not enough info. Give us some more details.

iv had the car 13 years restored it about 8 ago drove it a year or so it set for about 4 started it 2 months ago psut new plugs wire points cap coil and new carb when i it got the guy said it had been freshed up it sounds tight but seems like to me it has never ran right you can warm it up and from a roll put it to the floor and sometimes it will white smoke 50s other times it will just die been like that sense iv had it about to drive me crazy

My 72 owners manual says for low power, check: timing, dist rotor, warn dist shaft or cam, bad plugs, dirt or water in fuel line, carb floats not set right, bad fuel pump, incorrect valve timing, blown head gasket, low compression, burned or bad valves, bad coil or condenser, faulty ignition cables.
