GM TBI - 4.3 vs 2.8 liter

[ibeme at glasscity.net]

Does anybody out there know if the injectors that go into
the GM 4.3 TBI and the 2.8 TBI have different calibrated
flow rates?  I know that the injectors have the same form
factor and that there's two of them.  If you are careless
when rebuilding a TBI, you can mistakenly put the wrong
injectors in - i.e. 2.8's for the 4.3's.  I should think that
the 2.8's have a lower flow rate for the same open time,
but I'm not sure.  Anyone out there know?

Thanks,
John
