Old TRW Catalogue, Any body have one?

The link I posted quotes a '78 catalog listing for an L2308AF, described as a 427 Chevy 12.2:1 slug for a 427 Chevy open-chamber 2nd design. Meaning the 1st design would have to be in an older-than '78 catalog...
This pissing match, however Ford-informative it may be, isn't helping the OP....at all.
