Edelbrock Performer Series carburetors are designed to handle the rigors of daily driving while delivering consistant reliable street performance from day to day. They use metering rods to transition between circuits which means they are unaffected by engine backfires as they have no power valve to blow out, and the rods can be changed in seconds for easy tuning. And they STAY tuned so performance remains constant day in and day out.
