Chevy 6 intake manifold 6.09K viewsJanuary 3, 20170 LocatorF1 January 3, 2017 0 Comments When will production start again on your 63-75 Chevy 6 cylinder tri carb intake manifold? Has it been discontinued? Ordered one a year ago and it is still on backorder. It’s the last piece to my project. 1 AnswerActiveVotedNewestOldest 0 DMarv Posted January 3, 2017 0 Comments White Owl Speed Equipment has that manifold in stock.
