MPG Experience

By Martin Micheelsen - 04/03/2003 3:34:51 PM; IP 66.135.226.87

With several configurations of 390s (mild to wild) with automatic, 3.0 - 3.25 gearing, a relative small Edelbrook 625 carb, electronic ignition and aggressive attention to dial-in I was able to maintain approx. 15 mpg in mixed driving in a Galaxie. This was in a place where gas is $5-6 per gallon. Here my Cougar gets 11 mpg with an extremely tired 390IP - mostly short trips/daily driving. Even with the tired 390IP longer trips yield 15 mpg. If you build yours for daily use, dial it in well and keep a moderate gearing I would gues MPGs in the range of 13-15 are realistic - even with some playfullness.

This thread, so far...

OK - but it will vary with tranny type, gear ratio & state of tune. [n/m] -- Mr F, 04/03/2003
