If it were me i would get rid of the junk edelbrock carb and get a good 670 cfm holley street avenger carb that's more than enough carb for a sb 383 up to 550 hp
The sensor carburetor uses the sensors in its operation while the electric carburetor uses the electric current in its operation.
According to Edelbrock, the 2701 Performer EPS is designed for use with square bore carburetors (for those who don't know the difference between a square bore and a spread bore: A square bore has primaries and secondaries that are the same size; a spread bore has small primaries and large secondaries -- like a quadrajet). Edelbrock recommends a 600 CFM performer carburetor for use with the 2701 intake manifold. Edelbrock recommended part numbers are: 1405 with manual choke; or 1406 with electric choke and calibrated slightly leaner than the 1405 for daily driving & fuel economy. You can also use Holley carburetors as well (vacuum secondary or double pumper in the size of your choice).
Electric
It had an electric choke...chocks are for wheels.
Any of the new Edelbrock and Holley carbs should work well with a 350. If you have tuning knowledge of one of the brands, stay with what you know. The electric chokes that these come with work very well.
To install a carburetor with an electric choke, first, ensure the engine is cool and disconnect the battery. Remove the old carburetor and clean the mounting surface on the intake manifold. Position the new carburetor on the manifold, aligning the gasket properly, and secure it with the mounting bolts. Finally, connect the electric choke wire to the ignition power source and reattach any necessary fuel lines and throttle linkage before reconnecting the battery.
The electric choke wire connects to the electric choke assembly on the carburetor. It's a round, black plastic assembly that is on the side of a STOCK carburetor. There SHOULD be a connection on the "HOT" side of the coil that lets you connect the choke wire.
(305 displacement x 5250 rpm) divided by 3456 = 463 cfm carburetor 500 cfm x 3456 divided by 305 = 5666 rpm I would say if you are just using the engine for the street, a 500 cfm carburetor is more than enough. Perhaps an edelbrock with an electric choke would work nicely. The carburetor is only supplying the fuel. A longer duration cam, say around 200 degrees at .050 might perk up the engine a little and still let you run vacuum for brakes and automatic transmission. You would just have to read what others have done and look at performance parts companys online and see what people say.
Some had Fuel Injection with an electric pump and some had a carburetor with a manual pump. If it is FI it has an electric pump.
The carburetor has an electric choke that is possibly shorted.
yes. it has a four barrel computer controled electric carburetor.
probably your electric choke . take note the electric choke of these caburator are activates when there is no courant and disactivated when there is courant
