Hey everybody, my name is Eric Miller from Cascade, Iowa. I'm 24 and I farm and rebuild wrecked heavy equipment.  I started this build 2 years ago on limited spare time & tools. Goal is building the ultimate every day work truck / weekend warrior. This is my first truck and first build. Figured i better do it now before I start a family. I hope to have the truck done before my wedding this coming August..

I first got the motor a few years back from a Case IH agriculture sprayer that i bought and stripped after it had been hit by a train. The sprayer flew 90 feet and amazingly the motor was fine, except for the oil pan, pickup tube, and injector lines.  You can see the article of the accident here: http://www.kcrg.com/news/local/3191126.html

I've been wanting to drop the motor into something for a long time. I finally bought a 6" lifted 84 crew cab chevy with the frame already shortened rust free box cab and 1990 suburban power doors and front clip and 468 big block. But i ran into a big problem.. The vin tag for the dash got lost because a new surburban dash was swapped in and the old one was cut out and, well, it disappeared... Lucky for me a guy in town was selling his 89 crew cab chevy with 45k original miles that he bought from the Arizona swat force. He removed the bombproof swat center room whatever you wanna call it and installed a flatbed. What's great is it's never seen salt so it's in fantastic condition, inside and out. I sold the bed for $2000 and the engine for $1500.

Compound turbo kit is a massive S474 over a phatshaft 62 from industrial injection with a 3 piece manifold. I went with this kit because it's supposed to , as they told me, spool well and it looks like it would fit perfect in the c/k body with the large turbo up in front rather then down under the smaller turbo.

The whole truck will be painted chevy volt pearl white. I painted the engine red because it's cummins national color and it came from a CaseIH.  Not to mention it just looks awsome! I picked up the p-pump from a pullin truck that was gettin upgraded to a 13mm, so it already has all the goodies. The original AG pump wouldn't work because it didn't have an automotive governor. The old lines were mangled so i got .093 stainless lines to give it some lope. The injectors are SAC 7x14's should be plenty to fuel the turbos. I'm building an adjuster to connect to the manual fuel plate so i can adjust it on the fly inside the truck. This should help keep it streetable since it will be my everyday driver. I put an adjustable timing gear on the injection pump to help tune things in easier with a custom made billet cover.
I polished all the chrome work myself, just took it to a guy i know to have it all dipped. It's very cheap if its prepped and ready to be plated. The clutch is a south bend twin disk which will be bolted to the dodge nv4500 with a billet 1 3/8"'s billet input shaft and a 1st gen reman dodge 205 bored out with extreme duty bearings and chevy outputs.
As for the internals the cylinders have been bored 40 over and fitted with oversized low compression marine pistons. All new bottom end bearings and main and rods bolted together with ARP bolts and studs held together with a girdle. I sent the head out for fire ringing, 60lbs valve springs and titanium retainers and keepers.

Sorry all the pics are out of order but Photobucket's new site won't let me arrange them correctly...

Thanks! I hope it's worth all the work when it's done.

Sharp rig!  That's a baddazz pic with the claw in the backround!

Been awhile since my last post.. I've been busy working on converting the old barn full of junk into another shop. It's mostly done now, just moved the truck in over the weekend, i forgot how many parts i've accumulated!!

Here's a before:


And after
