Rochester Dualjet CFM

Hi !
Can anybody tell me whats the CFM for an original Delco Rochester Dualjet for 3.8 BOP V6? The number on it is
17081493
2577 DJU
It's a R-2/M2ME that was use from 1979@1987.
And what the hell the BOP mean after the 3.8 ?

Thank you:(

if its anything like the old dualjets that came on the 260s the correct answer is Way Too Small! seriously though, probably something around 250cfm

Thank you for the infos. I know its way too small for a 350 :) I just have one brand ew and wanted to sll it with a little info sheet of the carb.
Thx guys.
I found more infos on it Buick-Olds-Pontiac. 3.8 and on some Olds Serria 3.0l
Will try to sell it to a Honda ricer that love shinny objects :P

I pretty sure the CFM on that carb was 390

Thank you alls
