I have a stock cast iron intake manifold casting #3973469 date code H80 for sale.
This was used on the 270 HP 350 in 71 only and used on Caprices/Camaro- Z/28 and Corvette.
It is unmolested and still has original paint and grease. I have not cleaned it so I don't mess it up, so it can be restored to original by somebody that knows what they are doing. I know to most people this is as worthless as dog crap but to someone restoring a 71 Vette with a 350/270HP it could be invaluable.
Please call or email me for more pictures or questions.
