A system enabling the replacement of a 6.4-liter Power Stroke diesel engine with a 6.7-liter Power Stroke engine in Ford trucks is typically offered as a kit. These kits generally contain necessary components such as wiring harnesses, mounting hardware, and potentially modified fuel or cooling systems, facilitating the engine exchange.
Undertaking such an engine conversion can offer enhanced performance, improved fuel economy, or increased reliability, depending on the specific application and the condition of the replacement engine. Historically, such swaps have been pursued to overcome limitations or address mechanical issues inherent in the earlier 6.4-liter engine, leveraging the advancements incorporated into the later 6.7-liter design.
