The Edelbrock intake gasket #7240 is engineered for 1958–1965 348/409 "W-Series" large-port Chevy engines to promote optimum flow and reliable sealing. MP-2N micropore technology avoids solvents and creates a chemical-resistant synthetic fiber composite with high recovery under load, allowing the gasket to conform to imperfections with less flange pressure and featuring a nitrile bead for enhanced port sealing.
