i'm looking for a vehicle. there's a 84 4x4 pickup for sale. i don't know if it's a k10, 20, or 30. (probably not a 30 for the price). the ad doesn't give any more info than that. don't know what tranny, etc. (i'd like a 465) i'm thinking low to mid 20 for mileage. am i dreaming? i drive like a grandma, i don't squeal tires or accelerate hard. what gears would it have? i'd like to put on 32s for a daily driver wheeler. figuring 3.73 would be good forthose i think. i know 1800 rpm is best for economy, so i'll try to stay around that. i'm 21, this would be my first vehicle. it would be a daily driver do everything vehicle. i really appreciate your help.
