I still don't understand the NHRA logic on that one?????
The 69 Impala Sport hardtop is rated at 275HP while the wagon is rated at 263HP. They both have the same frontal area (drag) so the only difference is weight.
The 69 Chevelle also has the sedan and station wagon at different horsepower..
The different ratings for a Camaro vs an Impala or a Chevelle make sense because of the difference in drag.
I'm confused

Thanks I think. In my case the sedan and wagon are at the same HP now. Im thinking of asking for reduction to get my wagon in U at 4300 down some weight to keep up with 302 Fords. The Olds is now 207 up 69 HP over factory.
