I like the 'Historical Stock Theme',
And, with the......... 'in-the-trunk-options'.
If I remember correctly, around 1963 - the 1958 Pontiac was pretty much a 'done car',
and could be found on the Dealership back lots............in the 'discounted or unwanted car area'.
Suddenly with the increase activity in Stock Class Drag Racing in early-1964, the 1958 Pontiac was
now a 'hot old car' that you get for 'cheap' and to put it on the Drag Strip.
Especially with the 370/330 HP ~ '3 x 2 Barrel',
With the 4-Speed 'Strato-Flight' Hydra-Matic, it was a desired combination for the Chieftain in the
'D/SA' NHRA Class in 1964 and 1965 at {11.30 - 11.88 Wt/Hp}
Or the 'heavier' 58' Pontiac 'Star Chief' 4-Door, which was a perfect fit for the E/SA Class {11.89 - 12.49 Wt/Hp).
