RPM Air-Gap 2-R (1500-6500 RPM)
Designed for street 396-502 c.i.d. Chevrolet V8s with high-performance rectangular-port heads, the RPM Air-Gap incorporates our race-winning technology. The open air space separates the runners from the hot engine oil, and as a result, the air/fuel mixture stays cooler for a denser charge and more power. Includes rear water outlets, two distributor clamp locations and nitrous bosses. Accepts all late model alternator and A/C brackets for the street. For square-bore carbs only. No provision for exhaust heated chokes and no exhaust crossover. Available with satin, polished or EnduraShine finish.
