The Edelbrock Part #7521 RPM Air-Gap intake is designed for small-block Ford 289–302 cid and 331–347 stroker applications, delivering improved power from 1,500–6,500 rpm. The Air-Gap separates runners from engine heat for a cooler, denser charge; the 7521 features larger runners than the standard 7121 to benefit larger-displacement stroker engines. Includes nitrous bosses; no exhaust-heated choke or crossover provisions.
