took the k5 from hudson to divide colorado, almost a 200 mile trip. did some 4wheeling and stayed at a cabin over the weekend

so i want yall to guess what my miles per gallon was, figured we could have some fun with this

specs on the k5.

86 k5 with a mild 350 carbed no emissions, MSD ignition and box, headers, true duals, performer intake and cam, and punched out 30. getting exactly 14.7 to 1 at loveland colorado elevation.

running an sm465 tranny, 208 case, 1 tons with 4.56 gears and 35/12.5/17 BF goodrich Mud terrain Km2s

truck weighs 6k give or take 20 pounds (dairy scale) and i had about 300 pounds of supplies and me and the gf so lets say 6680


speeds were kept around 60-65 90% of the time,


here is a pic of the truck and where we stayed, good luck at guessing the winner gets a pat on the back, a fresh baked cookie and gets to be known as the MPG guru:wink1:


oh and a view from the hottub during the day :D couldnt see it very well at night ;)

Based on the specs of my rig and my MPG versus your rig and specs i'm going to say about 13-13.25 MPG.

EDIT: Has your speedo been recalibrated after the gear and tire change?

what carb? What grade of fuel? 465/208 origional to truck? what was stock rear end ratio? Really drive as many miles as you think you did?

oh screw it. I will say 16mpg because I want to hear someone claim it without overdrive.

Mine got 15 all day long with tbi350, 465/208, 3.08 rear end, and 31s...
