340 Gets Terrible Gas Mileage

The way I understand it, we still don't know what cam is in the engine, how high compression ratio is, what gears he has, etc. Given all that, 6 MPG in town may not be all that unreasonable. I know that I get 'about' 8 MPG in town and about 15 on the road. But 1) My 340 is at about 370HP, 2) I do know what my gear ratio is 3.55, 3) I know exactly how accurate my speedometer is (it is very easy to check - call your local police department and they will be happy to hook you up with a radar gun test), and 4) I don't care what my MPG is. I love driving my car. Now if it was running really poorly, and I was getting 3 or 4 I might be upset, but if it is running well and getting 6 MPG, that is OK.
