This is for a Good Used Original Chevy Corvette Q-Jet Iron Intake Manifold (GM Part Number 346250, GM Group Number 3.265) used in 1975 75 1976 76 1977 77 1978 78 and 1979 79 Chevy and other GM V8 SBC Engines. Couldnt find thre date code but did'nt really look. Its a Non EGR smog intake that was degreased years ago. Light coating of surface rust that will easily clean up. WYSIWYG. Call if interested. Thanx
