MPG experiment....1976 Dart Lite

MPG on the last tank, 19.60 per odometer, 20.18 corrected for tire size.
This was combination of city and highway. AM highway was cruising at 55 MPH for the most part. PM highway is more slow and go, 25-35 mph average.

Changes....
Transmission fluid (drained out 5 ounces, took 85 to fill it back up )
Differential fluid (ok fill level but dirty)

Both were done mid tank, so their benefits were partial. I was hoping to get new exhaust run this weekend, but it might not work with finances.

Next up will probably be the HEI ignition modification. I am also going to duct air up to air filter housing, to see if that helps.

I am not quite ready to dive into the timing modifications just yet. I have to work my way up to that (new, scary )
