Sometimes, you want to keep the look or feeling of a classic chassis, but want a lot more performance than even a full race modification of original engines and components can give… reliably. If so, it could be time for a major engine swap, modifications, and fabrications.

Complete engine and transmission swaps give significant improvement of power and reliability to old cars. Often modern larger displacement aluminium engines weigh less than the smaller iron casting original engines, giving better weight distribution, more power, and with modern fuel injection and electronic ignition, even can be cleaner and less harmful to the environment.
