The Edelbrock RPM Air-Gap intake for 351C Cleveland V8 engines uses race-proven Air-Gap technology to separate runners from hot engine oil for a cooler, denser charge and improved power on street or race applications. It is engineered to complement Edelbrock 351C Performer RPM cylinder heads (#61609, #61629, #61625) and also works with 2V and 4V cast-iron Cleveland heads for direct-fit compatibility in 1970–74 351C applications.
