What MPG are you 340 guys getting?
With My 340/416 sroker with a 750 Brawler on a LD340 intake, (engine dynoed at around 530hp), 727 reverse manual VB with 4400 stall and 3.73 gears with 295/55/15 MT drag radials on the back, I got 16mpg during my 101 mile round trip to Mopars In the Park this year after spending some time tuning/jetting. I was really happy with that!
Since then, I've added a GV Overdrive and my last 140 mile cruising trip, it came out to 18mpg. Planning to put 4.10s in the rear soon and will see what that does to it.
