I need to know which one to look for. I want to go with an electric choke, but I have not been able to find a non-electronic Q-jet which comes with the electric choke.
The crate motor is one of those Mr. Goodwrench hecho en Mexico engines which was manufactured in 1992 and is said to be 250 HP.

With about 150,000 carburetors to choose from, I have one on my own 350. However, since I detest electric chokes, I use a manual choke version.

Good carburetion is fuelish hot airThe most expensive carburetor is the wrong one you attempt to modify.

Put a cap over the vacuum tube.

The problem is finding one for a Chevy engine that has the integral choke in the carburetor. Most of the OEM Chevy carbs have a divorced choke mounted to the manifold heat riser passageway. I have used a carb for a Buick 350 at times, and converted the choke cover to the electric heated type. Don't use the gasket under the cover- - - -it prevents the heater coil from getting a ground, and plug off the vacuum port to prevent a constant leak. Route the voltage through an oil pressure switch so the choke heat shuts off in case the engine stalls during warmup.
