Notice specific reference to RAIII. Granted parts cataloging does not indicate what was on the original order sheets, however it is a GM publication. Whether GM referred to RAIII at point A or B, is not so much relevant to the fact that GM did reference RAIII.

Notice also 67 listing for Ramair, not just a matter of a pan in the trunk? I would imagine this meant cam in engine from assembly line.

GM is not an exact science, explore the facts with caution.
