NEW Carter 2BBL carb for 225 slant-6

Hi guys,
My buddy over here in New Zealand is looking to pull some extra power out of his one owner Valiant 225. Currently running a single barrel and it just doesn't quite get the umph he's after.
If anyone has one, or knows where we can get a NEW carter 2BBL carb with 4-hole mounting, please let me know
I prefer to do PayPal....it's easier for me, so any help would be much appreciated. I don't have feedback here yet, but I do have a Rating of 15 @100% on FBBO, and 290 @100% on fleabay....and I'm reasonably well known at FBBO. :D

And this is not normal, but here is a drive of the car in question when my buddy Cliff picked it up...

(only because a thread isn't worthwhile without pictures)
