AMC 290-401 V8 RPM AIR-GAP AMC (1500-6500 rpm)
Designed for 1970-91 304-401 c.i.d. and 1967-69 290-390 c.i.d. V8s, RPM Air-Gaps incorporate
the same race-winning technology as our Victor Series competition intakes. The air-gap design
features an open air space that separates the runners from the hot engine oil for a cooler, denser charge and
more power. Includes standard oil fill and PCV provisions as well as early air conditioning support bracket
accessory bosses. For square-bore carbs. No provision for exhaust-heated chokes. No exhaust crossover.
