When ya factor in the 3.73 gear things look a lot rosier. Figuring a 29” or 30” tire you were probably turning somewhere around 2500 to 2600rpm, but you were covering a lot more miles than I would.
I was coming back from jury duty this morning in my ’97 Sierra in 5th gear I was running 55mph and she was just barely over 1,200 rpm. That will give me bout 18-20mpg on the highway. That got me to thinking what that would look like I ran it in 4th (1:1) and had a 4.56 gear in it.

Stick it in the cargo hold p.j. and ride on back with my ”Big old wife” tonight, she’s in Phoenix for the day. We’ll have ya on the road back home after breakfast!

Ya know little buddy, I don’t have an inside vacuum gauge but I’d bet it’s kind O’ hard to keep it in the green when your doing 45 with a 4.57 gear.

Come on Dale, you been round here three times longer than I have. If ya know where to get a 3.08 (no way) or a 3.90 (next to imposable) or a 4.11 (real elusive) for a ’50, 3604 somewhere in the Chicago area or even with in a couple of hundred miles of here, then ya got the best kept secret. Mind you now, I don't want to change out the original axle housing.
