Pure Grunt

All our naturally aspirated testing was done with Dart's Kool Can dual-plane, open-valley-style intake (PN 4281100) that was port-matched to the 215 heads. The carb is a Holley HP 950-cfm vacuum secondary (PN 0-80497-1) with the stock 78-square jets, 6.5 power valves in both ends, and a 1-inch four-hole spacer. The only problem with the carb is the lack of a large vacuum port for power brakes; an adapter for a spread-bore Quadrajet might be a better off-road option. The valve covers are Dart PN 68000010 cast aluminum, which need holes bored in them for breathers. View Related Article
