Hi Darrell yep its a Speedmaster set, seems to be ok, at least the butterfly shafts are bearinged and sealed not like the OBX stuff. they do lack an idle air bleed so disregard the sentence that says they have one as they don't, or if they do i'm buggered if I can find it, but for a race engine they're not really relevant anyway..
good find on the old FF, when you get tired of going slow, you no my number lol.
cheers John
