Edelbrock part #2815 Super Victor intake manifold compatible with small-block Chrysler engines with conventional rectangular port heads like Edelbrock Performer RPM cylinder heads or Victor heads, this single-plane Air-Gap style manifold operates from 3500 to 8000 rpm. Testing has shown substantial mid-range gains over the current designs. The runners have been cast in such a way to insure enough metal thickness to allow for gasket matching and porting. Accepts 1975 and earlier waterneck only.
