Well. two years ago I paid $388 for a new Thickstun dual carb intake for my flat head.

Offy's version today is $459. though I would suggest the Thickstun is a better design. However, the Offy has theoption of being theoretically available. The Thickstun got made in batches and sold on Ebay till they were gone, then another batch would get made. Haven't seen a batch in sometime and with the way things are going now maybe never again.
