You're watching Dead Dodge Garage, and today ends with "y," which means we're tuning another big block to get it to run as well possible. It's an art I like to think I have mastered, and hopefully I can help the average viewer with a big block of their own understand the techniques involved. Anyway, while we're at it, we'll take a close look at the top of the line Plymouth muscle car from 1969, and try to catch all of the special details found on the GTX.
