It was a 69 only thing, perhaps related to the TH350 being new in 69? It could be that they had production limitations or perhaps the there was a question about the torque-weight capacity until they had actual in-service experience.
It was the same case with 69 Firebirds, 350 2bbl without AC used the TH350 but TH400 with AC.
