The Edelbrock RPM Air-Gap Dual-Quad intake manifold for 396–502 ci Big-Block Chevy engines with large oval-port heads (1975 and earlier) delivers improved breathing and power across 1,500–6,500 rpm. Standing 7/8" taller than low-profile dual-quad designs, its Air-Gap separates runners from the hot valley for a cooler, denser charge, making it suited to street builds seeking broad-range horsepower and improved high-rpm response.
