Ford 260-289-302 V8
RPM AIR-GAP 302 (1500-6500 rpm)
Designed for street 289-302 c.i.d. Ford V8s, the RPM Air-Gap incorporates the same race-winning technology that's been used on our Victor Series competition intakes for years. The air-gap design features an open air space that separates the runners from the hot engine oil resulting in a cooler, denser charge for more power. Includes nitrous bosses. No provision for exhaust heated chokes and no exhaust crossover. Aftermarket 4-bbl carbs are not compatible with Ford Auto Overdrive Transmission (AOD) unless used with Lokar bracket SRK-4000. Available with standard finish or new EnduraShine finish for a look you've go to see to belive, see Optional Finishes.
