I'm seeing 'a lot'.

And that is 'not' comparing the 1967 ~ 383/325 HP to the 1968 Road Runner/Super Bee 383/335 HP either.

Current NHRA 'Stock Class' Horsepower Factors

* 1967 ~ 383/325 HP ........ 280 HP
* 1968 ~ 383/330 HP ........ 295 HP

Those numbers look pretty close to correct and true Factory Horsepower.
