Edelbrock part #2975-BP Victor Jr. intake manifold is excellent for many applications from drag to circle track racing. This intake manifold provides maximum performance for engines with standard port location, iron and aluminum cylinder heads. The low-profile of the #2975-BP works well in applications with minimal hood clearance and where 1" or 2" spacers can be used for performance tuning. When carb spacers are not allowed, the #2999 should be used. The Edelbrock Victor Jr. #2975-BP is a single-plane, high-rise intake designed for maximum race-winning power at higher engine speeds.
