Re: What kind of gas mileage do you get with your 67-72?
Averaged around 10 mpg with my 72 K10 when I drove it, empty or loaded. Stock 350, 3.73's and 31" tires. Expecting just a bit more with the new LSA, 5.38's and 40's. But with over 3 times the HP and TQ I do not care. My previous 72 K20 with a slightly warmed 350, 4.10's and 38's averaged about the same 10 mpg.
