H.O. Firebirds were Built for 1968
Short answer: The only firm figure is from the 1968 Engine Production Log: 2,099 total Firebird H.O. engines (1,415 4-speed + 684 auto). Everything below is estimated from the coupe-to-convertible ratio:
| Variant | Est. |
|---|---|
| 400 H.O. (coupe & conv) | 2,087 |
| 400 H.O. convertible | 350 |
| 400 H.O. 4-speed | 1,400 |
| 400 H.O. auto | 650 |
| 400 H.O. conv w/4-spd | 250 |
| 400 H.O. conv w/auto | 100 |
Exact counts would require researching the PMD Billing History files for the 348 engine option, sorted by body style and transmission — unlikely while that data is privately controlled.
