My 1970 Buick has a 7.5L engine, a 455 bored .030" over. The fuel tank is 20 gallons. It is a carbureted engine.

I get 200 miles to a tank on average in that 1970 Buick (drove that car for over 300,000 miles so I have had a couple fill ups), which is quite poor mileage at 10mpg average. Around town I get more like 8mpg, 14 or so highway. How in the world do I get better mileage in my 45 year old car than you do in your LS3?

My Camaro is quite similar to yours, an LS3. 44 miles a day five days a week (to work and back is 44 miles), and I do not even use a tank of gas to do it. I drive 70% highway, although I am usually doing 20 mph or less in stop and go traffic half way each way.

Something is wrong with this picture...your car gets less than 7mpg on average in 'sedate' driving.

Well, the .800 lift cam, twin 76 mm turbos, and Siemens Deca Racing injectors at 227 lb/hr doesn;t help... The new motor will be somewhere just over 2K rwhp at full song...

Took me 3/4 of a tank to go 252 miles on a trip. I averaged 17.87 miles to the gallon on that trip; using 14.1 gallons (our tanks are 18.8 gallons, 1/4 tank is 4.7 gallons, 4.7 times three is 14.1, 252 divided by 14.1 equals 17.87 mpg) Didn't use my DIC to do that. Filled the tank before I left, had 1/4 tank when I arrived.

That works out to 335 miles to a full tank.

Coincidentally my average mpg is calculated by my DIC as...17.7 mpg right now.

On the open interstates with cruise control set at either 78 or 88 depending on which state we were in on the way to Sturgis, SD, the average was in the 22.1 range (after resetting avg number to remove town driving from the computer). So sometimes it would read 430 miles until empty. Normal driving in my semi-rural home area shows just over 300 miles when I fill up (17-18mpg). Of course when you run up the rpm's in the gears, then forget looking at gas mileage, just have fun. Basically besides the 6 vs 8 cylinder everything is all about how you drive it. For some reason, I seem to get better mileage when my wife is in the passenger seat........................
