GM Model 700 Throttle Body

[Orin B. Harding]

Does anyone have any information on the injector used in the GM 700 throttle 
body?  I'm trying to use one on a 1.8L MGB engine and the one I have (off a 
2.5L from a Grand Am) isn't flowing enough fuel at WOT.  I need one that 
will flow about 55#/hr.  Any suggestions?...Thanks..
