I don't have an agenda.I just find it fascinating the massive differences in horsepower factors with cars using the exact same engine.40 horsepower difference based on body type?
40 horsepower difference based on transmission type?
It doesn't matter if they were at 340 or 380,I still wouldn't ever outrun one.

The Champ lives in Donaldsonville, La. not the place you mentioned. Louisiana does not have counties.

The horsepower differences between sticks and auto's are reflected in the index's. But it was originally to make up for the way auto's and sticks were back in the day. Now with the evolution of auto transmissions I think the sticks are the ones that need the half a tenth. But then I run a stick. You know there is something up with the horsepower when a engine combo that is 75 ci smaller rated at less horsepower in the same class can be 3 tenths and 4 mph faster. Just saying.

Ever seen the specs on a 455 Olds?

Your point? If it was such as easy combination to run way under...everybody and their brother would have one. Fact is, there are only a couple in the whole country that are active, myself included.
