Hey guys, doing a quick bare bones swap into a Chrysler I picked up with new tires, new interstate battery for $300 with a blown 2.7.
i started Friday night, rebuilt the lh6 and dod deleted it, did some test fitting with the engine and trans. Crazy amounts of room. With the truck pan sitting on TOP of the subframe I still have to a of room, but I went ahead and notched the subframe to drop it a couple inches. Rebuilding the 60e today, then it goes back in for good and hoping to be done today/tomorrow.
In for this. I too have considered this. I DD a 5.7l Charger right now, nice cars. I can't knock the motor either. They made so many of them the value has fallen out entirely, they are everywhere cheap.

Keep going!
agreed, dirt cheap right now. Comfy and roomy too lol, and honestly at 37xx # it’s about as heavy as an f body lol.
So far I have the Chrysler temp gauge, speedometer, fuel gauge, all working with the ls stuff. Believe I have the tach figured out also, and the oil pressure is just a dummy light so I’m debating what to do there. Doing the harness in the morning and then dropping it all in
I'm super interested in the wiring side of things if you care to share what you learned.
Ill know for 100% sure when the car is running, but here is what I’ve gathered so far.
i left the Chrysler pcm and harness on the car.
Without an engine in the car, I grounded all the leads that were grounds on the engine. I then placed the temp sensor in. Can of hot water and watched as the temp gauge rose. So that’s score one, I just drilled and tapped the passenger head and threaded the Chrysler sensor into one gm head. Temp is done.
my car has an oil pressure light, no gauge. I hooked the Chrysler sensor into the pan adapter just above the filter for that.
speedo, there are two speed sensors on this trans, Input and output speed sensors. I took the output shaft and slid it in the tail housing and lifted it up with the vss, and wired the Chrysler speed sensor into the gm vss plug and then spun the output shaft in my hand and was able to read up to 10mph and vary it up and down spinning it slower or faster. Great! But I have no tuning ability to adjust speedo that way. So I’m also going to try and run the ls pcm signal out wire to the Chrysler vss that way and see if it will work so I can make adjustments in the tune for the speedo. Fuel gauge is untouched and works good.
tach. This is the one I’m afraid of. From my reading the Chrysler used cab bus from pcm to cluster.
thr Chrysler crank sensor uses a 3 wire 5v, ground and sensor wire just like the ls. So I’m going to piggy back the Chrysler crank sensor wires to the ls harness crank sensor wires and see what it does. Will know more on that in the next few days .
Today I isolated the sensors and the wiring I needed for those sensors, and removed all the rest of the harness as I don’t need it and don’t want it cluttering things up.
No problem, stay tuned in the next few days for confirmation in all of it. Will be driving it shortly. I’ll have more updates on things I did with heater hoses and the like also
chrysler oil pressure sensor is 3/8 npt, I drilled my oil pan adapter to 1/4 npt and installed it.
as you can see here the Chrysler trans line are on the driver side, I plan to
just use the Chrysler line and cooler in the radiator. You can see below my solution.
Not the prettiest way of making it work, but I couldn’t find anything other than plastic t’s and I wasn’t about to bury a plastic t behind the engine for the heater core. Won’t be seen once installed
I cut the old ends off the fuel
lime and made my own line that attaches via 200# pinch crimps with fuel injection line. Using the factory in tank regulator setup as it’s a 60# system, and I’m going to leave the Chrysler pump
even for
now
You can see my solution for the trans lines here, I’m going to put them in loom so they don’t run a hole in them.
Drilled and tapped for coolant sensor
lastly ill be using the factory rubber motor
mounts and building stands for them for the ls engine.
Good to see someone being creative and just making the **** on hand work instead of getting out the credit card, want to see this one up and running so I can steal your ideas!
I love the improv moves! You do what ya gotta do that WORKS....
Thanks man! Appreciate it, gunna be a cheap swap
for sure lol

Agreed, I enjoy making stuff instead of buying stuff, and I enjoy posting about them Incase it ever helps anyone!

Thank you! It’s been different one for sure, my first mopar lol.
More hurdles to cross today. Shifter cable was way too short, started looking and the cable runs from the shifter, all the way up to the top of the firewall and then down to the trans and comes in to the trans from the front. I removed the cable, drilled a hole in the trans tunnel
where it would be on an fbody and fed the cable through, problem solved.
I WAS planning on welding a tab to the top of the DBW pedal and attaching a throttle cable too it, but wouldn’t you know it, it’s 100% plastic unlike GM. So I guess ill
be making a pedal
assembly from scratch. Trying to get all this done before I put the engine in for obvious reasons,
