Please help identify those two carbs

[Frank400]

I'd like to know two things about those two carbs:

17056258 and 17057258.

 I need to know if  they are single MAB or dual MAB, and I need to know if they are 750 or 800 cfm.

  I know all the differences between those carbs, it's just that they were offered to me over the phone and the guy at the other hand is of no help and can't send pics. 

   thanks guys.

   Frank.

 Tell him to send you a good photo of the primary bores of both carbs. As single or dual, that I don't know. Sorry.

I know but he's of no help and can't send pics. Hope Cliff sees that post and knows if those are dual MAB or SMAB .

I'm showing the 7058 is an 800 cfm.  Don't have MAB info.

Those are both the larger castings and have two pairs of MAB's.....Cliff
