Anthony,
I watched your video, what a cool truck! I see where you where aiming for mid-20 MPG, were you successful?
Do you re-do the factory GM harness for these swaps?
or
Use a aftermarket harness?

Owner is currently getting 22mpg but 24 is achievable as I just put a generic tune in it and the owner wanted the truck tuned so he could drive it last summer.
I re-work the factory harness by removing un-necessary wires, adding relays, OBD2 port and chk engine LED, etc. I also re-route the wires to remove/streamline the factory worm mess (snakey) layout.

Thank you for the reply Anthony.
Question: Regarding the 5.3 w/4L60E , I just brought home a 2005 out of a Avalanche today and it is going into my Chevy II Station Wagon.... what rear gear ratio would you run to potentially obtain 26+ MPG?

My choices of rear gear ratios are : 2.76 - 2.97 - 3.23 - 3.55
My Wagon has been a Drag car for 35+ years and has a Chrysler rearend under it.
Thank you for your help!

yeah sweet swap! im helping a buddy with a 52 ford f1. just put a zigs mustang 2 front in it. and planning on a 4 link rear with coil overs.
engine is a 04 tahoe 5.3 2wd 4l60e. 87k on it. all sensors, harness, computer, fuse boxes...all accesories are with it.
question---ive read the rear ends in 51 (?)---to idk..maybe 53 are dana 44's with 3.73's in them. the truck was a flathead v8...im thinking this rear will hold some power...or does someone think different???

Custom fabricated tubular mounts. Pretty basic, just a plate, ears, bushings, tube and a plate bolted on the crossmember. Go to liquid iron industries for a sample of the mounts.
Stock rear ends are pretty beefy. Just need all new lines brakes, seals and fluids.

I have a '51 with an L92 / 6L80 - don't come anywhere near 24mpg. I get an honest 11 to 15.. Many build pictures attached below... Might give you ideas about steering column. Had to snake around the exhaust and I built a short steering column as I did want a horizontal flat steering wheel. Fabbed custom engine and trans mounts. Had to modify the trans tunnel cover significantly to clear the trans. I put the engine as far back as possible. About 1/4" from the firewall at the driver's rear valve cover.. Weight split is 55 / 45 static F/R.

It put down 352 rw ft lbs and 340 rwhp engine is stock. I was thinking the larger displacement 6.2L caused the reduced mileage.
Others called his Dyno conservative. Quite a few SoCal users here use Cunningham.
My average is probably 14 mpg. And I do get on it regularly but very rarely see WOT.
