Post up your Early 64-66 Barracudas!
The red #15 Barracuda looks like Mike Ritz's Team Starfish Barracuda. I built two engines for that car. Unfortunately the second one ended up all over the track after he had some valvetrain issues. The moral of the story is, when your engine guy tells you the valvesprings need to be upgraded, you listen...or pay the price.
