There are a lot of things a person can do to their car to make it not quite stock. Many will do a restomod, replacing original parts like brakes or steering with more modern versions. Some will upgrade the engine. At this past season's Wheels Back on Monmouth event in Newport, there were a few cars that could be classified as no longer stock. Here are a few cars that took the engine swap idea to a new level. They include a 1950 Chevy Delrey, a 1957 Chevrolet Bel Air, a Ford Maverick, and a couple 1955 Chevy Bel Airs.
