Just got my 70 c10 SB on the road to home with "connect and cruise" package from GM. Its running its original 3.73 gear.

My old engine was rated at 200HP - the LC9 is 325HP. Don't know about torque but it feels like there are 2 307's under hood.

Drove home from installers on back highways running about 60 mph to avoid tickets. GPS said I went 104 miles - took 4.6 gallons at pee stop = 22.6 mpg.

Less than 1000 miles on engine.

Happy camper.
