Many of the great muscle car innovations were born from a desire to beat the competition at the drag strip. In the early '60s, automakers were cramming the largest and most potent V8 motors they had into ordinary production models, then stripping out weight, upgrading suspension components, and installing wider tires to create specialized track cars. Such was the case for Chrysler when its engineers took a 1963 Dodge 300 and dropped a Ramcharger 426ci V8 under the hood.
