I found this at http://www.dailyfueleconomytip.com/?p=195
"According to the National Highway Traffic Safety Administration (NHTSA) the average gas mileage for new vehicles sold in the United States has 23.1 miles per gallon (mpg) in 1980 to 24.7 in 2004. This represents a paltry increase of slightly less than 7% over the 25 year period." This is amazing and sad. All that emissions crap and technology junk that gets rammed down our throats and that's the best they can do? I had a 77 Z/28 about 10 years ago that had 10:1 compression, a 286 cam, all roller valve train, Trick Flow Twisted Wedge heads, Edelbrock Performer intake and carb, HEI, TCI Streetfighter trans, and 3.42:1 posi and it got 18MPG highway! If I can do that, you'd think these car companies could do better. Karl Groves Master Certified CIW http://www.karlcore.com Will Work For Parts: http://chevelle.karlcore.com/detail.php?id=3
