Performer 302 Intake Manifold Small Block Ford 302ci 4-bbl Square-Bore Carb Flange (EGR) Idle-5500 RPM Range Designed for carbureted 302ci Ford V8s with EGR. This intake manifold is for 302 4-V V8s; 1983-85. Replaces the stock 4V EGR manifold using the stock 4V adapter. Can be adapted for 4V use by using Edelbrock's 4V EGR plate p/n 350-8053 and the OEM EGR valve and gasket. Edelbrock's EGR adapter kit p/n 350-8017 and Ford p/n E4ZZ9A-589E spacer may be substituted for p/n 350-8053 EGR plate (1983-85 H.O. Mustangs/Capris come with this Ford spacer). For 4V off-highway non-EGR applications, use Edelbrock's carb spacer p/n.
