Lake Speed's Final Ride: Running His 1993 NASCAR Ford Thunderbird Wide Open (In Car Cameras)

What happens here

The problematic twin-blade carburetor is removed and replaced with a 'reliable' Holley 830 carburetor. This swap is intended to improve engine performance, especially in the turns. After installation, Lake Speed Sr. starts the car, and the idle is adjusted from inside the cockpit. The car is then driven onto the track for the third and final session. Lake Speed Jr. expresses optimism about the new carburetor's performance. During the session, Lake Speed Sr. is black-flagged due to smoke coming from the car, which turns out to be an oil leak from another loose fitting. Despite the setback, Lake Speed Sr. expresses newfound confidence in the car's handling and grip in the turns, feeling he can 'push his limits' due to the improved performance.

Goal: Install the new carburetor and assess performance during final track sessions
