My 307 Olds fits in Cutlass sedan and station wagon. Will asking for reduction in 1 car effect both cars if granted.
I'm thinking no...but with that said, NHRA is still a mystery to me..

1969 Chevrolet 441 head 255HP is rated by NHRA at 280, 275 or 263HP depending on body style ...

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
