In 69, any B body with manual transmission without A/C and the RR or SB with either transmission and without A/C got the 335 horse version.
mid year change on B bodies ?( but SB and RR ) is not on dealership databooks... or I missed
in any of the cases... optional or standard on this setup ?
69 B bodies with manual tranny and no ac got the 335 horse. Not optional, not mid year change. Plants like standardization and easy. Having a 330 horse manual no ac was a bit of overkill. It would be just as easy to use the 335 horse manual version rather than assembling a 330 horse manual version.
Dealer books don't get into specific applications.
