Look at your PHS 1969 Master Order sheet and tell me what it says for Option 348. I am guessing it says the same as mine... L74 400 HO 4 BBL V-8
RPO codes are what the car was built on, not text. When PHS runs a report on '69 Ram Air III Firebirds, how are they identified? I guess that is the key to the solution.
