Could We See Big Block Gas V-8 & V-10 In New Trucks Again

Diesels are a whole lot cleaner than they used to be. If you put your nose by my exhust pipe you wound not smell diesel. And there is no way you can make black smoke.No matter how hard you push the pedal, if you get anything black it will be the tires burning. I had a Ford V10. It couldn't pull my 30 ftr uphill in the mountains of Az. and it got a high of 8 mpg. Now I get an avg of 14. If thats not better for the enviroment I don"t know what is. Bad for the guy making fuel, they don"t sell as much.
