71 429 out of a thunderbird
From an old 70's Chiltons manual, for Ford, Mercury, Thunderbird it says
71 429 2bbl 10.5 comp. 320 HP, 460 ft lbs.
71 429 4bbl 10.5 comp. 360 HP, 480
71 429 4bbl Police Int. 11. comp. 370 HP, 450
71 was the last year of the high compression engines.
71 was also the last year that the old gross HP rating system was used, SAE net ratings took over in 72.
