Designed for street 396-502 c.i.d. Chevy V8's. These intakes stand 7/8 taller than the low-profile C-66-O/R dual-quad intake and offer performance improvements in the 1500-6500 rpm range. The large runners feature our unique Air-Gap design that separates the runners from the hot engine valley for a cooler, denser charge. In dyno tests on a ZZ 502 with intake #7522, heads #77485 and #2261 Rollin' Thunder hydraulic roller camshaft, we made 602 hp, 15 hp more than the Performer RPM intake manifold #7163. Both intakes are also available as a complete manifold and carb kit, see page 131 for more information.
