Truck is really coming together nicely. I was about to offer you my factory shroud extensions but clearly had no problem fabricating your own. Curious did the LS engine placement allow for you to keep the 4l80 in the same factory position?

it’s ok work, doesn’t compare to the stuff you do sir, but I appreciate the compliment.

Factory shroud extensions? I had no idea that’s a thing? Is it an H1 thing or a Humvee? I do believe I should have run the shroud all the way around the fan, but this is what I had here. We will see.

I kept the transmission exactly where it was. Not having to mess with the trans crossmember or the driveshafts is pretty nice.

For anyone watching this and taking notes, it’s a whole lot easier to run a returnless fuel system than using the return style I had already. I was able to swap my rails for a returnless style thanks to a local guy here. I could have used what I had but also had concerns about using the factory fuel pressure regulator built into the rails. In conjunction with my Aeromotive pump I just had thoughts about it long term not being the best.

New fuel tank showed up, glad that’s done. Ordered some headers and they didn’t fit the best. Ordered another set that I think will be better. Sure I could cut the “ears”’off the transmission but I still don’t like the angle the collector is at.

The new headers showed up, wayyy better placement that the last set. Got plenty of room to run tube These are F Body headers….

Hydroboost lines are done! Originally I got a pump to hydroboost line from a 2500 Chevy and it was a little too long. Found out a m998 Humvee hose is perfect.

Was traveling for work and came across some Humvee parts for sale. Scooped up a turbo doghouse for $80 and some flappy doors for $150. The Tubro doghouse fits perfect with the LS truck motor. I don’t know what these doors are actually called, but I really wanted a way to access this area when the floor panels are installed. Pretty happy . Just need to clean these parts up a bit and track down the proper mounts for these rubber tie downs.

Trying to get the fuel system done as well as the exhaust, so while the fuel tank and soon to be removed muffler are out of the way, I’m using this as an opportunity to go ahead and remove the camber shims. Not terribly difficult, but a few of the bolts are a little hard to reach. I just loosened everything and tapped the mounts with a hammer and they fell right out. I did cut a 3/4 wrench down for this. If I had the time and patience I’d definitely weld some of these bolt lockers on the mounts, I had no desire to unbolt the control arm to do that.

Driver side is done, glad all that is behind me now. Is it interesting that there were more shims on the passenger side than the driver? Everything is more square now, but toe needs to be adjusted.

driver side one shim, passenger side 3.

Exhaust, fuel system, wiring, that’s all that’s left to do….

half the party is here:

Really loving how this wiring is going. My plan is to have the dash look like a regular Humvee, with the ignition switch being used and analog style gauges. The ignition switch has 3 leads coming off it, battery power, accessories, and momentary for the starter. I plan on run the accessory lead into a small fuse panel. This will give me the ability to wire up a few things neatly rather than trying to tap into one wire. We’ll see how it comes out.
Got all my wire from Wire Barn. All USA GXL stuff so it’s good!

just need to plumb the fuel system, a little wiring, and I should be able to see if it runs!

using push lock fittings for the fuel system, not a fan of the braided fuel hose, so this should work perfectly.

I am using all of the original HMMWV gauges in my 12V Terminator X LS swap. (in addition to a digital dash to monitor/log more details and have GPS). The problem I ran into was the 12V-24V converter I used for power to the gauges bit the dust, so I have to find a better DC step up converter.

 

[sail78385]

The analog style gauges Holley sells are a little pricy but they all daisy chain together and tap into the Holley harness. Should be pretty clean when it’s done. I didn’t see the point in trying to reuse any of that stuff, but it would be cool!

Yes the Holley gauges definitely make for a cleaner install (and look better). I had to use 2 coolant temp and oil pressure sensors to get it working. Are you using the Holley GPS Speedometer?

I will be, yes. If I hadn’t jumped up to 42”’tires I would have kept the Humvee speedo.
