I still have a bunch of question marks. I don't drive crazy like alot of people here do, I only go to about 2500 rpm and thats it. According to the p/o, the original 4.10's were swapped for 3.73's.
'73 stock 350, SM465, 3/4 ton 4x4...and I swear that I can get close to 18 on long highway trips, If I keep my foot out of it (which I usually do). But, since I never go on long highway trips in my truck, I never get that good of gas mileage. I'd guess 14 or 14 on the highway to and from work and school, and around 10 in town.

Here's how much of a grandpa driver I am- I consider opening the Qjet's secondaries a special occasion, that rarely happens.
