Not to be an @ss, but, Cams+mods= no need to worry about mpg. If mpg is an issue, your best bet is to leave it stock.

Why do people mod a v8 sports car and worry about how much miles per gallon they will get?

Thats because most of your mods help the air to flow better, making the engine run more efficiently. And your 3.73 help to run the engine at a bit higher rpm, closer to your 4.6's power band. So your car does less work to produce the same power.

Bottom line, going fast costs money...how fast do you want to go?

Crower Stg 2 PI SC cams, 4500 RPM stall TC, 4.30's in the rear, 20 MPG city, 24 MPG highway. If I was to put the 3.27's that the car had originally, there is no doubt in my mind that my car would be back to 30 MPG on the highway like it was stock.

Because some of us can afford only one car and also want it to be fast.

Cams MAY drop 1MPG....MAYBE. I got 27 MPH highway with cams and full boltons. 25MPG on the way back with teh A/C on.

Now I get 25 highway and probbaly ALOT more since my 3.27s gears are back in.

ONLY mod where I noticed a drop in MPG was the 3.73 gears. Now with the 3.27s, my car gets ALOT better milage, but ill have to check.

id imagine it would only be 2-3mpg worse if you are an agressive driver.

Cams and gears can hurt fuel economy, but most others will help fuel economy if you don't keep your foot in it more.

In my 97 GT, I just got 22mpg in mixed driving (about 60% highway). In the summer, I got 27mpg once, but I was short shifting and driving 70mph.

LOL no I do...all the time actually. But I dont think iv ever actually adveraged less than 20MPG. Car always requires 4-5 gallons per 100 mile trips to/from work. Around 4 gallons if Im easy on it, and around 5 when I beat on it alot.
