730 variations

[Eric Aos]

After several weeks of lurking, and reading through the archives, I have
a question. I am working on doing an IR Pontiac. It seems the ideal ECM
to use is the 730. I have read in several places that the best setup is
90-92. I have a feeling that just saying Camaro will double the price of
the parts, would one of the 6 cylinder applications be the same? Is the
difference in the ECM, or is it just the Memcal (or is that Mempack ?).
