On 5/18 he got 6.2 miles per gallon,lol, he must have been racing.
Hey 340 is that your fuel record sheet? you used to race your rt I recall.
That was the actual record from the Challenger in the ad. (never my car)
I took my A66 340 Challenger to Raceway Park in Englishtown only once; did a low 15 second quarter mile in totally stock form with about 70k on the car. Never measured mileage at the track, but messing around in town got me about 10 MPG.
I had a 440-6pk Challenger, automatic, 4:11 dana back in the day. That car on the other hand did low 14's quarter mile runs without a lot of tuning and was getting 5-6 mpg on quarter mile runs.
I had a industrial area street near my house that was pretty quiet that I measured off a quarter mile and tried a few runs late at night. I went through a tank of gas doing about 7-8 runs with the 6pk. Didn't measure the mileage in any kind of "formal" calculation. (Broke the left motor mount that night too)
