Available to me I have the following truck.
1998 Chevrolet 2500 Cheyenne
5.7L vortec (CPI) engine (130K)
14 bolt rear (3.73) w/ positraction
I own the following truck:
1990 GMC FS Jimmy SLE
350CUI TBI engine (113K)
TH700R4 (Under 10K)
NP241 Transfer case
10 Bolt rear (3.73)
10 Bolt front (3.73)
Previous owner decided that a telephone pole and a tree would be the
best method to stop his truck from rolling ('98).
Engine starts, he says it runs smooth. This is just my preliminary
look, so I didn't ask him to start it.
I may be able to own the entire truck for around $500.
What would it take to stuff this 2x4 engine into my 4x4 1990 GMC FS
Jimmy with a non-comptuer controlled transmission, and OBD I as
apposed to OBD II? Remember that I will be recieving the entire truck
- so harneses/processors/et all. will be available.
Things that I think will be a problem:
Tranny mount? Will I be able to attach the "riser" or whatever from my
tranny to the end of the 4L80E then attach my NP241 to that, or will I
Will I need to cut a new drive shaft?
Isn't their posi traction the one that needs a 200RPM difference
between the 2 wheels, so it's kind of annoying? But I would asume
still better then completely open.
Will the axle from the '98 be able to bolt up to the '90? I'm asuming
all I would need to do is get an adapter U-joint, maybe new U-bolts to
attach to my springs after I cut the old ones.
My truck is slightly sagging in the rear, would the springs off the
'98 fit? I realize it wouldn't be as smooth a ride, and I'm not
looking to increase my GMVW - just looking to be cheap.
If I also remember correctly this engine is the one with the intake
manifold leak problem, so whilst the engine is out I should probably
look into replacing this?
Any other things I'm missing, besides the fact that I'm crazy?

The last two were nicked from a Corvette site, so I don't know if they
