Horsepower Reduction?
If a motor fits into multiple body styles and 1 body style asks for HP reduction will all body styles receive reduction if they are less then .5 under index?
My 307 Olds fits in Cutlass sedan and station wagon. Will asking for reduction in 1 car effect both cars if granted. |

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 |

Just one more question.... Why do you believe that that wagon should have a lower horsepower rating than the sedan??? The class is sorted out by weight to horsepower. Just sayin' |

Bob, one of the determining factors is wheelbase. Impala wagon has longer wheelbase than Impala hardtop. 69 Chevelle 2door has shorter wheelbase than 4 door sedan and wagon. 69 Camaro has shorter wheelbase than Nova. Ya can't make this stuff up! |
Re: Horsepower Reduction?
Does a wagon have more aero drag because of the long roof and side windows? It seems like it would.

Re: Horsepower Reduction?
Just fil out the form and send it in. Its easy. Doesn't hurt to ask especially if nobody has gone fast with the combo in a few years.
