The only real way to know your air / fuel ratio for certain is to measure the exhaust with a wideband Oxygen sensor. In this case, this super clean and freshly restored 1969 Pontiac Firebird came to the V8 Speed & Resto Shop to have the air / fuel ratio measured and the carburetor tune corrected on the dyno by our technicians. The car is running a Pontiac 455 V8 and is hooked to a Tremec T-56 6-speed manual transmission. Fuel is provided with a Rochester Quadrajet carburetor, and the suspension and brakes have been upgraded for better ride and handling.
The V8 Speed & Resto Shop team analyzed the air / fuel mixture and tuned the carburetor for maximum performance, as well as optimized ignition timing.
