Watch The Sloppy Mechanics Make 992 Horsepower To The Tires On Their Junkyard Colorado

We dig the Sloppy Mechanics. Not just because they clearly know how to have fun and make power, but also because they do it their way. Instead of building things that intimidate people because they are so perfect, they build things they want to because they are cheap, fun, weird, or all three. This particular Colorado makes 992 horsepower to the wheels and is powered by a junkyard 6.0L LS with boost. You gotta love that! And they are using mostly stock, and original, parts including the head gaskets, and head bolts. Brave, and cool.

We’re pretty sure the 6.0 has a Megasquirt based system¬†controlling it, as that is their typical go to, and we approve. And for those of you who don’t believe this is possible on stock parts, remember that Richard Holdener made over 1200 on a stock 4.8 on the dyno at Westech. Over 1300 on the 5.3, and they both made well over 100 pulls on the dyno over 800 horsepower. I know, I was there.

Yes, this one does develop a noise, but still ran, and we’re sure it’s a fix that won’t require throwing it all away.

Watch this.

    The noise was a bent rod in #3 – it made slight contact with the crank. Matt made a subsequent video of the tear down. Piston was fine – he just put in a new (old) stock rod.

      Actually, there were 2 or 3 “less bent” rods on the 1, 3, 5, 7 bank. There is a subsequent video where he uses a dial indicator in order to check how high the cylinders were rising in the bores. He replaced the bent rods with some leftover rods from earlier broken engines. He also shows his technique for dropping cylinders into the bores and he gives his opinion on reusing “torque to yield” rod bolts (he does). Lots of good information in that subsequent video.

    This guy don’t know nothin’. Everybody know the turbo exhaust goes thru the RF fender on an S-10/Colorado. (See my build thread)

    Still, pretty impressive. Glad it’s fixable.

    think they decided the failure point was a headgaskets or the headbolts on the driver bank

    still trying to find the weak point of the stock bottom end just needs more fuel
