I searched the archives and I am left with some questions.  On the
corvette cross-fire injection, what ECM is used?  How are the IAC(s)
done?  What is the big difference between a 8747 and 7747?  I know the
older big-block's came with 90 lb/hr injectors, so does the 8747 have
larger inj. drivers?  Thanks.

Andy
