I’ve been having problems with this from the start. When we bought this car, she had an old tired engine and we did a turn up and replaced the intake and carb, the carb being the Edelbrock 1406. Car ran great except when pulling off from a dead stop under normal acceleration, like at a traffic light or stop sign in traffic. The car hesitates and stumbles, but give her a little more gas and she takes off.
Well, thought it may have been just the old engine. Put a new GM Performance 290 HP 350, GM Performance mechanical fuel pump, MSD distributor and ignition, wires, plugs and a K&N air cleaner. We transferred the new Edelbrock intake and carb to the new engine. Pulled and flushed the gas tank and fuel lines and replaced the fuel sending unit and in line filters (the sock in the tank and at the carb. Still have the same problem. She stumbles and hesitates under normal acceleration. Nothing aggressive, just pulling off from a stop, like at a light or stop sign in traffic.
Any ideas? I’m thinking, maybe trash in the carb, maybe the fuel pressure is too high or is this carb just a piece of crap since I’ve had the same problem on both engines?
