my new 440 has a strange problem. if you accelrate at full thrtle from a stop in scond gear arund 3000 rpm it misses/bogs untill it reaches 3800 then it seems to clear up. when you first hit it it goes like heck for a few seconds. 800 cfm edelbrock, 10:1 compresson, 727 2600 stall 268 xe cam.

5/16 fuel line
