Wish I could get that MPG with my 283. Mine is closer to 11/12. I have the tendency to reduce gas mileage claims by 25 per cent to get realistic. Just sayin.

WAIT, Don't take 25% away from my 6 mpg... I'll hardly be able to get up to freeway speeds before I need to stop for gas! LOL...
On a side note, I bumped my iming up 2 degrees and kept the speed down (mixed in some mom-freeway driving) and got 8 mpg on the last tank.
Anyone know how much engine temp affects gas mileage? My engine does not have a thermostat (or it is stuck open) I need to pull it apart and put one on when I replace all the hoses.
