Advance Adapters has an article in their Jeep Conversion Manual on Saginaw
steering conversions.

Don't rule out the automatic, if it is what you really want, until you get
the measurements on a TH350 and do the gear ratio engine speed math.

It wouldn't hurt to cruise the used car lots where you live, and see what is
available in a newer model. You could call it "research". Sometimes they
have coffee and donuts.

What specificly didn't you like about the Buick V6? This is the
de-facto standard engine swap of choice so I'm curious what it was
that gave you grief- Doesn't matter what tranny you put in there, the
top gear ratio is still going to be 1:1, see "overdrive" comments
below-

The D18 xfer case is plenty strong for what you're talking about. the
only problem with them is that the intermediate shaft needle bearings
tend to chew up the shaft after about 30K miles, a hardened
intermediate shaft from Novak fixes that quite nicely.

The T90 if rebuilt properly should last as well as anything else you
can stick in there. An auto tranny is going to give you grief with a
ridulously short rear drive shaft & depending on the transfer case may
need a two piece "Commando" style front shaft to get around it.
Unless you really hate shifting or really need to creep over big rocks
I'd pass on it.

Likewise the Dana 25/41 axles should also hold up fine for your use,
everbody rags on the weak axle shafts but they are in fact the same
piece as found in early 44s. As for the ring swap get a Warn/Saturn
overdrive instead, you get the best of both worlds for a lot less
money :).

Not to dissparge the level of expertise here but I would suggest you
also solicit opinions on the ****** Tech list-

I'll admit most problems were related to the installer (me). I've
learned a lot in the past 12 years, so I think this time it would be
much better. Main problem was I still couldn't cruise at 60, since I
didn't change the gears. Back then I thought the V6 would give me
higher RPMs, like 6000 instead of 3000 (double my speed). Dumb
mistake.

Good to know, I'll check that out before I give the go ahead to the
rebuild guy. He probably knows about these parts also, so I'll see
what he thinks.

I'll just have to measure since I'm getting conflicting info from each
person I ask. I think a lot of people are trying to put the auto in
the newer rigs with the straight xfer case, and I've heard they fit
better with my offset case because the rear output is lower. Seems
like most people think the T90, along with other stock jeep trannys are
all weak. I guess even the stock trannys with the stock V6, from the
factory, broke a lot.

If my axles were in good shape I'd think more about keeping them. I
think the overdrive is a 30% increase, which is just what I need:

60 * 70% = 42 (so I'd be able to go 60 with the same RPMs I currently
get at 42, which 42 is around 2200 RPMs if I remember correctly
(haven't had the tach on for a while))

I'll check that site, but I know overdrives aren't cheap.

I'll admit most problems were related to the installer (me). I've
learned a lot in the past 12 years, so I think this time it would be
much better. Main problem was I still couldn't cruise at 60, since I
didn't change the gears. Back then I thought the V6 would give me
higher RPMs, like 6000 instead of 3000 (double my speed). Dumb
mistake.

Good to know, I'll check that out before I give the go ahead to the
rebuild guy. He probably knows about these parts also, so I'll see
what he thinks.

I'll just have to measure since I'm getting conflicting info from each
person I ask. I think a lot of people are trying to put the auto in
the newer rigs with the straight xfer case, and I've heard they fit
better with my offset case because the rear output is lower. Seems
like most people think the T90, along with other stock jeep trannys are
all weak. I guess even the stock trannys with the stock V6, from the
factory, broke a lot.

If my axles were in good shape I'd think more about keeping them. I
think the overdrive is a 30% increase, which is just what I need:

60 * 70% = 42 (so I'd be able to go 60 with the same RPMs I currently
get at 42, which 42 is around 2200 RPMs if I remember correctly
(haven't had the tach on for a while))

I'll check that site, but I know overdrives aren't cheap.

Hadn't seen this one yet, thanks.

Thanks!

 

If you got a Buick V6 professionally race balanced and installed a different
cam, I'll bet you could get 6,000 rpm out of it. ;^)

Remember that while an overdrive increases road speed at a given engine rpm,
it decreases torque at the rear wheels. The factory overdrive (fifth gear)
in my 2.5 liter Wrangler is pretty much useless for that reason. So if you
install an overdrive or regear, you will probably need to increase engine
displacement to compensate.
