NC Scout LS swap -newb

Ok, part of the reason for this thread is to just show the progress of my build. The other part is to hopefully have some input from the veterans on this kind of stuff. I built an old drag boat once, but I've never done anything like this. Swapping out old technology for new, totally foreign to me. So, I guess the final reason for this thread is just to show that it can be done by a newb. Now I'd like to think I'm mechanically sound. I own a CNC shop in Raleigh and we do quite a bit of prototyping (still very different from this). I've been doing tons of research and will continue to do so, but like I said, I'm a total newb to this stuff and I'm sure I'll have some dumb questions along the way so bare with me. Anyways, enough of the BS and into the build.

I decided to jump on a 2 for 1 deal when I came across a couple Scout IIs, both for $2k. On one, the body was in pretty good shape with little to no rust, has primer so it needs paint and came with locked 245 and a very solid/clean interior. The second was covered in rust (flintstones style) with a SOA that terrified me and a locked international 392 (not factory). So I pondered what to do, jumped on this forum and asked around which lead me to the purchase of an LS lm4 5.3 out of a 2004 trailblazer with about 30k miles. It was complete pullout, computer and all for about $1,000. Would have liked to have gone 6.0, but this being my first build I set a budget (which I'm sure I'll shoot over in no time, but that's part of the fun). I kept the Scout with the good body/interior and parted, what I could, from the "rust bucket" scout. So now I have trim, glass, doors, hardtops, knobs for dayyyys. I sold the rustbucket for $1,100 on Craigslist and got the bulk of my cash back. Needless to say I was pretty happy about that. Where I screwed up was pull the Dana 44s from that one and swapping them with the smaller 35 on the one I kept.... Shit. So now I'm in the market for some Scout 44s. Ok, now that you know a bit of the history of this build I'll get to the good parts. Let me get some pictures together and that will be the next post. Stay tuned!

I would look hard at the complete anything scout conversion kit. I am not associated with them, but if your time is worth anything at all and you want to knock it out quickly just spend the $3k for the whole mess and be done with it. I just finished mine and I am super happy with it. Unless trial and error and fabbing are your thing, no need to reinvent the wheel...
just my 2 cents...

Do it man!

I'm just starting an LT1, 700R4, Dana 300, 5.38 gears in the Dana 44 and 14 bolt, new painless wire harness, painless LT1 harness, rock ram power steering, radiator, heater / AC, dash gauges... and whatever else I find along the way. My crawl ratio should go from about 18:1 to 43:1.

I'll probably start a build thread soon.. but it's needed. I have a bad piston ring in the stock 304, the 727 is burned up (inadequate cooling off road), and i have an LT1 with T56 sitting in the garage.

Progress Update

I know its been awhile since my first post. My wife got sick and my world upside down but everything is back to "normal". Now that winter is pretty much here its time to get my ass in gear and the scout rolling! I have made little progress since my purchase but over the next few months its overhauling time.

Whats been done:
  • Scout has been completely disassembled and labeled.
  • I trashed all the old wires.
  • The scout tub was removed from the frame and cleaned
  • The frame has been cleaned, sanded, wire wheeled to death, and coated.
  • Old motor mounts have been removed and spots prepped for new mounts.
  • I've also purchase all the necessary mounts for the LS and Transmission swap.












Yanking the 6cyl paper weight....

If you need a hand with anything I hate scouts but I've helped build a couple. I'll probably just help because I'm eventually going to need some Cnc work

Need Help!

Its time to purchase the rest of my drive train! I have a Vortec 5.3 LM4 out of a 2004 Trailblazer with approximately 30K miles. I know I need to purchase a 1990-1991 NP241 Pass Drop transfer case but I'm having a hard time finding one. I found a refurbished one for $800 shipped with core charge but that seemed kind of high. I am now in the market for a transmission. I'm trying to decide on a 4l60e 4x4 vs a 4l80. I found a remanufactured 4l60e with upgraded HD parts (650hp rating) for $1,500. Also, I know I need a 27spline but is there a specific year I should be looking for??? ANY HELP would be greatly appreciated. Thanks in advance!

My local auto recycler has a Send me an email when vehicle X arrives feature on their web site.

I set up notifications for 1990 and 1991, GMC and Chevy, Suburbans and Blazers (yeah 8 separate 'subscriptions')

Took about a month of waiting, but one finally showed up, I got there and the NP241PSD was still in it, I pulled it. $50.

I ordered a complete rebuild kit from the same place I got my SYE from.

What are your plans for the scout? Stock style driver, lite wheeler, more hardcore?

I would recommend getting d44s from a Jeep or Chevy. I prefer the additional width and added caster. Also replacement parts arent such a pain to find.

Plans for the scout:
-My goal is to have an expedition/camping type setup.
-The scout needs to be able to get from point A to point B via common roads and be a capable unit as an off-road trail rig. If there is such a thing haha.

Also, I would kill to see a picture of your rig with those axels. I may wind up going that route. Any particular years I should look into?

IIRC, Here is a pic after we completed the swap years ago.



The chevy swap is almost bolt in for SOA and is ~69" WMS. d44 would be pre-80. A FSJ front axle is bolt in SUA and is 60-65" WMS. If you want to stay close to stock width and SUA, I would get a pre-80 wagoneer front axle, but it will be 6 lug. A J10 or cherokee axle will be a few inches wider. Chevy will be 6 or 8 lug. Any of these can get 5 lug swapped on if you want to retain the stock rear.

search craigslist for transfer case and transfercase. There has been a pass drop 241 32 spline for sale on and off here for months for 50 bucks.

Your scout is awesome! Do these axels work with the transfer case pass drop setup?

The 70s jeep and chevy are pass drop axles, so no issues. Ford and 90s+ Dodges were driver drop.

I think it depends on the tire size. I believe that SOA rides better than lift springs, but has more axle wrap than SUA. We started with SOA and 4" triangle springs. It was too tall for the front driveshaft to fit with the short drivetrain. We took out some leafs and lowered it.

If I did it again, I would do SOA with a softer 2.5" spring. Something like YJs or the like. But I would run fullwidth again.

If you are planning to stay in the 31-33" tire size, I would get a waggy 44 front SUA with a 4" type spring. Convert the front to 5 lug and run the stock 44 rear.
