I’m satisfied if I average 13-15 on the highway. I will stop for gas at 200ish miles, but try not to go less than an 1/8th before stopping. If I put a load, or have long hills, and the ol girl drinks like a sailor on shore leave. Doesn’t matter though, she ain’t goin nowhere

I run a standard 350/4bbl TH350, and 3.73 diff
