someone offered to by my twin SU's yesterday, but doesn't want to get the manifold how much are these going for (their the twin inch and a quarter type)

2-500 dinero depending on the condition of the carbs....that usually means the carbs, linkages and aircleaners.

Not to rain on my own parade but:

The inlet manifold (if genuine Cooper or cooper s type) in unmolested and good condition as yours is (not ported out to 1.5" at the carb face like some) condition will fetch between $75 to $125 on ebay. If lynx or other aftermarket brand, subtract $20 to $40.

Dealers usually want around $100 for an ordinary one, up to $200 for a good one. (genuine)

Most people in the free market will probably offer you anything from $50 to $80 (either type)

That being said, the inclusion of a manifold with the twin su's on ebay has only bumped the price up by $50 or so on average.
