I'm getting ready to do some major upgrades to my newly acquired 1968 Wagoneer and I need some advice.
My plans:
I want to build a good driver. I'm at least 1.5hrs away from any decent trails/backcountry camping so this will be more of a driver than a wheeler. I want to leave the exterior just as it is and upgrade the drivetrain. I'm planning on a 4" lift and running 33x10.50 tires. I'm swapping in a 2005 5.3ls engine and I'd like to use a 4l60E overdrive if possible. I bought a 78 Wagoneer for parts and I plan on using the axles to gain power disc brakes and power/tilt steering.
Info on my Jeep:
1968 Wagoneer
Bone Stock
232/3-speed manual
Dana 20 transfer case
Dana 27? and Dana 44 (tapered shafts)
4.10 gears
My parts Jeeps:
1978 Wagoneer
Bone Stock
360/TH400
Quadra Trac (with low range)
Dana 44's
3.07 gears
70ish J4000
Buick style TH400/dana 20
Engine swap parts:
2005 Chevrolet 5.3/4L60-E (2wd)
I have quickly figured out that an LS swap is no where near cheap or easy in one of these Jeeps. The engine swap its self doesn't bother me, its the transmission/transfer case/axles that have me stumped.
I'm planning on putting the 78 QT axles in my 68 to gain power disc brakes and a better rear Dana 44.
So far, I've come up with these options:
TH400/QT -
will need to convert to a chevy case/rebuild and adapt to LS engine
QT I have will probably need a rebuild
may not need new driveshafts
700R4/QT-
will need to buy a 4wd 700R4 and adapt to LS engine
will need 700R4 to QT adapter
QT I havewill probably need a rebuild
will need to adapt TV cable to my drive by wire engine
will need torque converter lock up controller
will need new driveshafts
4L60E/QT-
will need to convert my 2wd trans to 4wd
will need adapter to convert 6 bolt housing to 4 bolt(700R4 style)
will need 700R4 to QT adapter
QT I have will probably need a rebuild
Will need to re gear axles
will need new driveshafts
4L60E/Dana 20
will need to convert my 2wd trans to 4wd
will need transfer case adapter
may have D20 to QT rear axle angle issues
will need D20 output shaft/housing upgrade
will need to re gear axles
will need new driveshafts
TH400/Dana 20
will need to convert to a chevy case/rebuild and adapt to LS engine
may have D20 to QT rear axle angle issues
will need D20 output shaft/housing upgrade
may have D20 to QT rear axle angle issues
will need new driveshafts
4L60E/NP241-c
will need to find/buy NP241
will need to re clock transfer case
will need slip yoke eliminator eliminator
may have NP241 to QT rear axle angle issues
will need to re gear axles
will need new driveshafts
As you can see there's no easy or cheap combination. I'd really like to use the electronic 4L60E transmission if possible but it pretty much adds another $1500+ to the cost of the build plus I will have to re gear both axles. Are there any other combinations I'm missing with the parts I have? What's the best/cheapest combination with what I have to work with?
