Mileage

[GetX'd]

I only got about 5 mpg out of my 440 six pack. And that after a dyno tune. That car is a gas hog. I’d be happy to be getting 10 mpg quite frankly.

For what it's worth....my RS24V0A******* GTX gets about 7-9 MPG at ~ 60 mph @ 3000 RPM and 4.10:1 Dana 60 gears. The car is 440 0.030" over with 11.0 pistons, Crane equilivant to Mopar 292° 0.509" cam @ 4° Retard. No vacuum advance and 35° total all in at 2400 RPM. I run a blend of 93 octane pump gas and Sunoco leaded 110 octane fuel. I wish it would be better....but WTF...it only gets approximately 600 miles per year.....not a deal breaker.
