Fare thee well

The time has come to say goodbye to the 1987 Chrysler Conquest. It had some good runs, but I have too many cars, and it’s just a heap. So it went to the scrapyard.

Now that the conquest is out of the garage, the Arrow can get some love. Time to pull the motor, and get those bearings replaced.

But wait, why don’t I throw the Comanche axles under the Comanche and get it off Jack stands. Great idea! So I did that.

I like how it sits. But it has the og rear axle, 2.something gears, Spring over swapped and the 2wd front axle under it. The only 4wd axle I have is 3.73 gears, so I didn’t want to put that under it. I also threw the 4inch front lift on it.

But wait, there’s more…

The maroon 85.5 conquest is giving up its motor. I pulled that tonight. I forgot how easy this pulling Motors and swapping axle stuff really is.

Whew. That was easy. Now it’s time to focus on what’s important. Dinner!

Shrimps and grits. Delicious.

Let there be light!

So the arrow still had “test lights” in. That is, 35w low on the driver side, and high on the passenger side, a 100w high on the driver side and a 55w low on the passenger side as if that’s not confusing enough. So now it’s running 55w low hids, and 100w Hella bulbs on highs. I had already installed high amp relays in anticipation of going hid.

It’s really hard to capture the cutoff on a fence on uneven ground.

More Arrow dash

The built gauge not matching was driving me nuts, and the wood grain just didn’t look right. So I got all matching gauges, and coated the dash with bed liner. I think it came out nice.

The gauges are; exhaust gas temperature, boost/vacuum, rpm, volts, and air fuel ratio. Some day I’ll address the actual dash pad.


The arrows dash was in need of some help. The digital gauges were to bright, the boost gauge read -14 no matter what.

I pulled it out and ordered some different gauges.

Now there is room for five gauges. The fifth hole is there, I just need to cut out the wood grain peel and stick cabinet lament.

I also replaced the radiator with an oem style copper/brass one.

What you’ve been missing

Not much. Actually, not much, so the Comanche is drivetrain less, and the purple jeep is about to be, and the broke jeep is just, broke. In order to get the arrow out of the garage, something has to move. So the arrow snuck out carefully with the aid of a jack.

I’m running eight pounds of boost, on the stock 2L block, crank and rods, with new pistons, a non jet valve head, conquest cam, and Megasquirt throttle body injection. It runs well. The new radiator is on the way. Along with new gauges because the bright blue digital ones overtake the road at night.

The above was filmed with a potato for informational purposes.

So the 5.9L is coming together, and I’ve got the mounts ready to be installed in the mj chassis. I need to get rid of its old drivetrain so it’s out of my way.

But the engine is assembled, I need to change the transmission filter, but otherwise it’s ready to line up in the mj chassis.

Spring is in the air

With 50s and sunny, February is starting to feel like spring! But since this is Michigan, it could be winter tomorrow, so seize the day!



Got the arrow all aired out, so I could rearrange the garage so I have room to walk and tear open the 5.9L for the jeep.


That went pretty smooth. Until an intake manifold bolt broke off in the head. But whatever, I’ve got the technology to get that out.


Looks like the crank has been turned before. I didn’t get to checking the bore yet.
