    This is the pin that keeps the swing outs in position.

    And, a catch can I put together.

    KIMG0703.jpg

    Most of the work putting the new powerplant in the truck is boring, hot, sweaty misery. So, I'll take some pictures of the fun stuff and make it look like a walk in the park when I post them. That is how the internet works, right?

    The LT4 is in the truck. I'm wrestling with all the little bits, intercooler tanks, so on. No major modifications to the fuel system were required.

    Looking good! What kind of power numbers are you hoping for when it's done?

    I have no intentions of modifying anything, so 650 HP/Torque at the flywheel. Maybe a tune would be in order once the warranty is up.

    I haven't had much time to update this thread and I don't think anyone really cares, but I've got nothing pressing to do at the moment. I managed to suppress the rebellion on Xtrar 5 and the virus we engineered to wipe out the sentients on Arghba 214 worked even better than we expected with near 100% mortality rate.

    So,...

    KIMG0022.jpg

    Bits and bobs need made. This thing has a liquid to air intercooler, so I bought a huge setrab cooler and stuck it in front of the radiator.

    KIMG0047.jpg

    It comes complete with a small coolant pump that has to live somewhere.

    KIMG0048.jpg

    And I need a great big tank for all that coolant.

    Body shop painted the tank, but might would look better crinkle painted? I've no idea why sideways.

    KIMG0119.jpg

    Well, I needed a new subframe and why not make a bombproof skid plate of it? And, I'll need to service the truck.

    KIMG0057.jpg

    That is 3/16" chromoly steel.

    KIMG0059.jpg

    The -12 fittings were a no go and they go to and from the sump tank. The front view that ties into the motor mounts.

    KIMG0061.jpg

    The entire underbody will be protected from stumps, rocks, and zombies.

    Now, the oil lines run right next to the header on the passenger side. No way I'd want a hose running through there and there wasn't room for it anyway. So, hardlines out to the front.

    KIMG0126.jpg

    KIMG0128.jpg

    I had to turn down some barbs to attach the hose to keep engine vibration from doing what it does. Of course, some welding is involved.

    KIMG0133.jpg

    And attached a hose via crimp.

    It looks like this.

    KIMG0138.jpg

    KIMG0140.jpg

    Then, I had to build these things. What a pain in the neck. I tried some fantastically nice headers that didn't fit. So, I build these with routing around an external slave cylinder.

    KIMG0144.jpg

    When I say these took a lot of time to build, well it did. But my welding has improved...

    By a lot more than I can actually do...

    KIMG0176.jpg

    KIMG0177.jpg

    The exhaust is all but sorted. The welder did a fantastic job and it certainly was not me. I am hopeful that cracks and other problems are not in my future.

    Okay, everybody likes a catch can. Since this engine is direct injection, the PCV system is important. I don't want oil and gunk coking up the intake valves.

    But before that I forgot to post a picture of the headers I built. I had to route the passenger side exhaust over the transfer case, which was somewhat tight. I used pie pieces to annoy a friend.

    KIMG0073.jpg

    And the driver side header.

    KIMG0096.jpg

    KIMG0097.jpg

    I had a starter to sneak around and a frame rail that was tight.

    As I believe I mentioned above, there is an external slave cylinder on the driver side that was in the way.

    KIMG0102.jpg

    The headers are sweet, but what a ridiculous amount of work to build them. I used cast elbows right off the flange to keep things tight. A key objective was to keep the exhaust up high and out of the way so that nothing bottoms out.

    Here is a shot of the sump tank--it contains 12 quarts of oil. I figure 2-3 quarts in the engine (it does have a small sump) makes maybe 4 gallons or so in total.

    I had to re-engineer the fan shroud and set up. I need a fan on whenever the AC compressor is on to avoid overheating the fluid in the condenser, so I have a small Spal fan tucked in down low on the driver side.

    KIMG0110.jpg

    And a monster fan on the top passenger side.

    KIMG0112.jpg

    I set them up that way to make room for the 4" intake pipe.

    The side of the tube is mounted on a small barb that I turned out of aluminum. I put a piece of silicone on it for to damp vibration and the tube on the intake rides on the barb.

    Back to catch cans. I wanted a large one with lots of coalescing media to catch as much gunk as possible. The can is 3" in diameter and 8" in length.

    The LT4 has a pcv valve under the supercharger that sends gases from the lifter valley and into the intake. I replaced it with a vented tube (top part) that seals shut the intake port.

    KIMG0155.jpg

    I have a line from each valve cover, one from the lifter valley and one more that might pull from the lower crankcase. All of the lines will go through the sump tank first, then flow into the center of the catch can. One line returns to the intake and the other to the port in the throttle body (which should be linked to the intake) with a one-way valve.

    I built a chamber with perforated aluminum sheet and welded it to an aluminum cup, which screws onto a hollow threaded dowel.

    KIMG0171.jpg

    KIMG0172.jpg

    I bought some stainless scrubbing pads at Lowe's and they fit about perfectly.

    KIMG0173.jpg

    KIMG0174.jpg

    And with the barbs installed on top.

    KIMG0178.jpg


    I wonder if it will work.

    The supercharger had to come out for a pulley change. The front accessory drive kit locates the pulley right on the end of the spindle.

    KIMG0190.jpg

    New pulley, stainless steel.

    KIMG0191.jpg

    Chevy is serious about keeping the pulley on there...wonder why.

    KIMG0192.jpg

    PCV mod, I had to interrupt the passage into the intake to avoid oil coking the intake valves.

    I finished the intake, for now. I will build an elaborate huge filter box that will connect to a snorkel, eventually.

    KIMG0195.jpg

    All the hoses for the PCV system are installed here including the catch can.

    Here is another.

    And the rest of the accessory kit. The Wegner kit was fantastic--great quality, fit, and engineering. That alternator makes 170 amps at idle.

    I'm thinking about gauges and so forth. This came to mind as a possible all-in-one solution:
