Volvo Penta GM V8 Engine High Rise Intake Manifold Holley 4 Barrel Carburetor. Carb is in excellent working condition. The intake manifold has some rust and grime but is is good working condition with no cracks. This intake is for late year Pre-Vortec GM Small Block Chevy engines. The 4 center bolts have a slightly different angle to make installation easier. Can still be used for older models but you must oval out the holes for the bolts to seat properly.
