68 Grand wagoneer Question

I came across a 68 Grand wagoneer motor, trans, and t-case. I was told it was a 327 V8(Chevy motor w/ jeep heads), The trans. is a jeep version of a turbo 400( it measures up to a turbo 400 for input shaft to out put shaft and the same bell housing as a turbo 400), and the T-case is a T-18. my question is was there a such animal?

If it's a 327 from around those years, its an AMC. It could be a Buick 350, as those were found around that year.

T-18 is a transmission, not a transfer case. A Dana 18 perhaps?

The AMC TH400 transmission is almost the same as the GM TH400. The housing has the AMC bolt pattern instead of GM. The internals are the same. All I've ever seen even have GM stamped pans.

Actually, it has a factory adapter ring. The trans is a Buick nailhead TH400 (different from Chev or the BOP pattern used in later GMs)

Also, it isn't a Grand Wagoneer, it is a Wagoneer.

The Grand Wagoneer didn't start production until 1984.

Carnuck is correct, it is a Buick Nailhead pattern with an adapter ring.

not sure what that one has in it but like others have said mine (also a 68) had the 350 buick with adapter, to a 400 turbo with a d20 t-case if you can take a look at them you could compare with the pics in my build thread to see if they are indeed the same parts.

his - 68' Wagoneer, 455 Pontiac, tons
hers - 00' XJ tail rig D44, C9.25, 4.56
ours - 01' WJ 4.0

Try listing them in the JF Classifieds.

This is how NAXJA Midwest Chapter elected officials like to treat their resident users and former multi-year supporters.

Rokjeep that could be a 327 it was an AMC motor called the Vigilante. It was a well proven motor that had been in use in the Nash rambler as a 250 cubic inch motor. It was bored and stroked to 327 in 1965 for use in the Wagoneer. It put out 250 horsepower. 1968 was the last year it was used and it was only used in the Wagoneer that year and in no other vehicle. In 1968 they started using the Buick Dauntless 350 V8 It was basically a 225 v6 with 2 more cylinders. It had less horsepower than the 327 but more torque so the seat of the pants feel with the 350 was much better and people liked it better. The 350 was available until 1970 in the Kaiser line, then was replaced by the AMC motors in 1971. The 350 was available as a special order for about half of 1971 (had to get rid of the ones on the shelves.)

The tranny would be the TH400 as mentioned above and the t-case is a 2 speed spicer 20. It is a nice t-case and is easily modified into a twinshifted case.
