David Freiburger's 1971 Plymouth Road Runner is all neato and stuff, but it's shamefully gutless. In this episode of Roadkill Garage, we’ll show you how to do some basic engine checks on an older car to find out why it's not making power. The guys will also hop it up a little with a vintage intake manifold and fresh Holley carb, then "scientifically" test the results.
