http://www.musclecaroftheweek.com - This week's video features a car that looks sedate as can be but reveals a startlingly different personality once the key is turned. The factory-built 1963 Ford Galaxie 500 Lightweight features an R-Code 427 for power, and nearly all the non-essential items have been deleted or lightened for better drag strip performance in the Super Stock NHRA class. There were around 200 built, and this one is as true to form as they come. One of the many factory lightweight Muscle Cars in the Brothers Collection.
