The video explains the modifications made to the carburetor, including fitting a Holley double pumper carburetor and an Edelbrock manifold, followed by a thorough dyno tuning process at Project Heaven. By introducing a lambda sensor, the team could accurately measure the air-fuel ratio, uncovering a seized choke flap in the carburetor that caused poor mixture control. Adjusting jets and fuel delivery components helped resolve issues like rich-to-lean fluctuations, improved throttle response, and eliminated engine stutters.
The tuning resulted in an increase in power output, raising the peak horsepower at the wheels from about 231 to 244. The driving experience is detailed with emphasis on the raw, analog feel of the classic muscle car, without modern aids such as power steering or disc brakes. New BF Goodrich white-letter tires were installed to keep a period-correct look while enhancing grip.
Overall, the video celebrates the unique appeal of the 1968 Dodge Charger through in-depth technical explanations and vivid demonstrations of performance improvements. It highlights the commitment required to maintain and drive a vintage muscle car effectively on modern roads, making it a valuable watch for muscle car enthusiasts and those interested in classic car tuning.
