Mopar got their 'tit' caught in the ringer when they claimed 335 HP for the 1968 383 Engine
in the Road Runner and Super Bee.
Everyone knew the earlier 383/325 HP and 383/330 HP (1967 and earlier 383's) had over-rated
Horsepower numbers. They were closer to 290 HP.
Chrysler could not rate the 1968 383 Horsepower properly.
The 1968 383 was closer to 310 HP, no matter what anybody says. The Road Runner and Super Bee
should have been running in G/S or G/SA in 1968 (11.00 - 11.49 Wt/Hp)
#3424 lbs. ~ 310 HP = { 11.04 Wt/Hp }
In January 1968, even Ronnie Sox said that the 68' 383/335 HP Road Runner would
get decimated in the NHRA Class of E/S or E/SA.
Sox & Martin refused to build a 383 Road Runner for Stock Class, and only had one for 'Show Only', which was 'not' NHRA Stock Legal.
