I get around 11 mpg based off the speedo, but the speedo is off so its probably getting worse than that. 355sbc, 292 competition cam, around 10.5:1 compression, holley 600 double pumper, and 3.08 gears (for gas mileage, its my daily diver) I swear I can see the gas guage move everytime I hit the gas, but it does get great smiles per gallon.
