Same info in the '69 truck info kit (pages 60 and 61). The footnotes at the bottom seem to show that emissions is likely the biggest difference. The LS-9 has AIR whereas the LS-8 has nothing or CCS. Of course, all have a PCV. My '69 3/4 ton only has PCV and is on the SPID as a LS8.
Also, see page 54 for performance data comparisons.
