055.jpgI doing an sas on a 87 isuzu trooper with a dana 44 and a 12 bolt . I am also installing 350 and th350 w/203 transfer case.AnY help or suggestions on v8 swap are welcome.
PICS COMING SOON ! :confused:
 
You're gonna destroy those axles
 
The stock rear zuzu 12bolt is stronger than the gm axle
 
Check out Pinkstons trooper, it has been through various stages and one of the early stages is similar to what you want to do. He could answer alot of questions for you on doing the swap
 
87 didnt come with the 12 bolt. It came with the 10bolt. The isuzu 12 bolt is a stout ass axle. run it. Maybe with a d44 front. unless you are going to run a carb motor, you will need to change gas tank and such, cooling will be an issue. Room in the engine bay too. Go for it though. I love old troopers
 
might wanna go with a 4.3 unless your gonna run tons

If you really want to prevent breakage then you could go with a gm 2.8......Or just have your rig torn apart all the time like me...:shaking:
 
I really hate to speak for chad on this...but he still has that trooper and I bet he would sell it. It has no drive train but its set up for a chevy small block already. Its a damn nice trooper too! got a full cage in it done right. I know I would like to see ti back together again.
 
Couple pictures of mine back in the day with a dana 44 front and isuzu 12 bolt rear with wheel spacers.

trooper

i built a s10 blazer almost identical to this with the same axles and they are welded. difference being it has 4.3 but the 350 i have for this was free and runs great . the blazer is still running 3.08 gears and we took it to ure and bashed it pretty hard even went up daniel and over kodak rock. he did break the transfer case adapter but that was due to a solid trans. mount and a broken motor mount . i have been running 10 and 12 bolts for a long time and have only ever broken the carriers on gov. lock axles . i even ran 44 boggers on a suburban with 10 bolts and pushhed it really hard to break the rear and after i broke it i drove the living crap out of it to get it out of woods on only front axle pulling and spinning dry dirt the whole time. maybe i just dont have a heavy foot and i try to go no higher than 38" tires but usually 33" to 36" or 37"
 
hmmm......I've seen 265s destroy 12 bolts multiple times
 
about to say... because 12 bolt isuzu axles from the trooper are a good start to an SAS.

but dude the V8?
might be too much for anything above 36's without chromolies.
I can see some flanges or hubs or ring gears taking some damage eventually. esp with the D44 up front.

I want to SAS (waay future) with something close to this but not an engine swap - regear to 5.13 or 5.38s and be done.

chrisM keeps pushing me to one-ton it.
there are a few guys on the planet with SAS frist gen troopers that have 3.4's and 4.3's with D44s up front but I think there are only a few V8's....
 
but the suburban i had had a v8 and 44's a 14 bolt in the rear and a dana 44 in front and i tortured it in deep mud and many hard surfaces also and remember the v8 is free and is complete from oil pan to carb
 
Tahoes...truck version

deep mut was your saving grace.....Tight turns big rocks...V8...snap

i really appreciate the help and advice but i am going to have to go with this for now because of budget and i never seen one of these under a tahoe , this came from a 75 k5 blazer and my understanding is they stopped using this in the early 80's
 
wonder if you can find something along the lines of a 60 or a 14 for the front that is the right width you want.
and keep the isuzu 12 in the back.

well might be out of the budget since a steering 14b if built would cost around 4k
