The prompt

Create a 3D CAD model of a Volkswagen AP 1.8L inline-four, 8-valve carbureted engine, including the engine block, cylinder head, valve cover, Solex/Brosol 2E carburetor, intake manifold, exhaust manifold, distributor, and nearby mechanical components. Focus on accurate external geometry and realistic component positioning, especially around the carburetor and exhaust manifold, for designing a custom heat shield. Exclude the battery, alternator, radiator, starter motor, and vehicle body
