Attempting the next best engine swap for 80s IMO

Why not just let me put a LM2 in your 100 series, I won’t charge labor you just buy parts so I can develop 100 series mounts

Its an intriguing offer but it would not solve all of my dislikes about the 100 series (I do generally like it though). When I purchased it years ago it was a compromise between me wanting an 80 series and my wife wanting a 200 series. Comfortable enough to run errands/take kids to school, but not so expensive that I would cry getting a scratch off road. Years later we are not in that situation anymore though.

I'm also not a fan of the IFS and the 100 Series head unit and lack of a good solution for it bothers me every time I drive it lol

I share similar sentiment wrt the 2UZ 100 series. They don't blow up? Is that a good reason to own one lol?

Make sure you do some thorough research on these LM2's and the newer version. Talk to diesel shops in your area about them. They see a side of these engines that may not be well represented in this thread.

I share that same sentiment lol Wife and I also like to try/build new stuff though and have owned in the neighborhood of 50 cars. People say the 2UZ will last 500K miles......thats great but I dont generally want to drive any one thing for that long so it really doesn't matter.

Ive been looking into the LM2 for several months now and a lot of the issues it has I believe can be rectified by some preventive maintenance depending on year of the engine prior to installation (timing chain, camshaft cover, camshaft position sensor) and the rest of the issues appear to be attributed to emissions and the truck electronics itself of the electronics OP is currently eliminating.

I do like your idea of reaching out to local diesel shops though as they will likely be able to provide quite a bit of info

So I’m using the factory tcase. With the LT1 swap I used Torfabs adapter and mounts.
So with this I used the same transfer case adapter since it worked with this 10 speed and just made my own mounts

Factory computer

Currently I’m just using a Edge monitor for gauges but I’ll be getting some Dakotas soon

Yes 14mpg with a 10 speed seems low
I’m hoping to get 30mpg they get high 20s in a full size Silverado with all emissions so I don’t think it’s unrealistic

3.0 take out you can usually get for around 5-6k

No DEF or Emissions stuff. I live in a non testing area

I was going to ask about that. so no DEF? Does it throw CEL's? I have that motor in my 26' GMC 1500 AT4x and love it.

Was there anything special needed to be done when swapping between diesel and gas? Just drain the fuel and good to go? Same pump, lines, etc?
