Just wondering if anyone knows what kinda gas mileage to expect from a 69 model Chevy C-10 250 6 cylinder with a 3 speed. I don't know what rear end is under the truck, but it'd be whatever came out from the factory.

At 55 mph I would expect somewhere around 14 -16, maybe more if its geared high (3.08, 3.23) maybe less if geared low (4.56, 4.11). Jumping up to 65 or 70 will knock it down 1 or 2 mpg.

I used to get 17-18 mpg with a '75 C-10 with a 250 and a 3 speed.
No idea what rear end it had, but the truck pulled hard all the way. The engine was box stock but no pollution control or cat. I had 30X9.50 15s on the rear on 8" rims on the rear. Faster or a heavy load could cause a big drop in mpg, though. I really enjoyed driving that truck. Now it is a parts doner for my '56, because that's where the same 250 is going.

Best wishes,
