The Edelbrock Thunder AVS Series feature spring-loaded secondaries and range from 500 to 800 cfm. All four models can be ordered with either manual or electric choke.

These days, we are so hyped up on EFI this and EFI that, we tend to forget that the good old-fashioned carburetor works pretty darn well and has done so for a multitude of decades in all the vehicles we love, whether they be musclecars, customs, hot rods, or 4x4s. Carburetors are also relatively simple, and easy to work on and maintain.

Edelbrock’s Performer also can be ordered with manual or electric choke, but in the seven-model series, there is a 750 cfm unit in the 500 to 800 range.
