1967 ~ Barracuda 383-S and Dart GTS-383 ~ 280 HP 'How can this be.'
1967
Interesting how in 1967 the NHRA allowed Ford to slide the 1966 390/335 HP 'S-Code'
down to 320 HP, with the same exact engine components.
In 1966 the Mercury Cyclone GT {390/335 HP} weighed in at #3315 lbs.
> 3315 lbs. ~ 335 HP = 9.89 Wt/HP
In 1967, the Mercury Cyclone GT {390/320 HP} weighed in at #3393 lbs.
> 3393 lbs. ~ 320 HP = 10.60 Wt/HP
1967 NHRA Class
> D/S and D/SA ....... 10.60 to 11.29 WT/HP
