Three cars that desperately need redemption get out to the track. Tony and Lucky dig into a Cummins-swapped '70 El Camino, a Hemi-swapped '70 Duster and a ratty '79 Camaro with a turbo LS, get them track ready and then just see what they can actually do.

The AMC V-8 has long been seen as a strong engine that isn't very durable. Tony and Lucky build up a 401ci power plant that will live to take whatever abuse they can throw at it, keep spinning happily, and make killer power along the way.
