Question Drive train after AMC 258 - 81 Cherokee buildup

Hi

My Cherokee 1980 needs a upgrade!

Now AMC 258 + T176 + NP208 Driver side drop


In garage waiting:

GM-D60 front axle passenger side pumpkin.
GM-14FF


New components as browsing the Internet:

This adapter kit was designed to allow the use of a GM TH350, TH400, or 700R transmission to the stock AMC straight 6 cylinder & V8s. This 5/8¿ thick steel plate allows you to couple any one of these transmissions, utilizing a modified flexplate (listed below), and retain the stock GM torque converter. The kit comes with the necessary hardware, crank bushing, and flexplate spacers. Flexplates sold separately.
AMC V8 & Inline 6 Cylinder Adapter Kit -AMC ENG. TO CHEVY-AUTO TRANS
Price : $303.60
Item# 716138
Mfg. Part# 716138

----------------------------------------------------------------------


Low Stall HD Torque Converter
B29-DE 700R4 1650 : 30 Spline $175.00


700R4 4x4 Heavy Duty Transmission 4WD
[MG304-700R4] $1,295.00

The 700R4 has a 3.06 ratio in first gear, which is 20% lower than most transmissions. The 30% overdrive will give a 30 to 40% increase in gas mileage on the road when compared to a 3-speed transmission


http://racetransmissions.com/store/p...products_id/30
---------------------------------------------------------------

This is the adapter required to enable you to mate the 700R4 Transmission to the GM NP205 Transfer Case
GM 700R4 Adapter Kit
Price : $483.00
Item# 50-6902
Mfg. Part# 50-6902
--------------------------------------------------------------

NP 205 locally $700


--------------------------------------------------------------
Grand Total:
$ 303.60 Engine TH700R4 adapter
$ 175.00 Converter
$1,295.00 TH700R4
$ 483.00 GM NP205 adapter
$ 744.00 NP 205

$ 3000.60 plus shipping to Philippines


-What is missing?

-Is this going to work?

-Other choices at a cheaper price?

Greetings from Boston!

A few details would help - are you keeping the 258? Are you trying to save/spend money, and what's your budget? What kind of vehicle do you want to end up with?

Since you seem to have access to Chevy parts (such as the axles), maybe you'd want to use the complete GM drivetrain (ie engine, trans, TC)? Looks like you really want an automatic - you may not be happy with the performance with a stock 258 and an automatic. Personally I'd rather have your existing transmission than any automatic. Your existing NP208 transfer case is a decent unit ...

Subic: why not just put a GM t-case in, that way you end up with pass side drop to go to the D60.

Options

Hi

For the time I will keep the 258! I know its under power but for now there is enough problems..

The NP205 is available locally thats why its an option. Also a 3pcs T19 with Dana 18 or 20.

Yes it maybe would be better with a complete GM drive train as one package.

What do you suggest regarding GM setup and yes I prefer a automatic but no chain transfer case if possible.

The plan is to have 38 x 15 x ?? or larger tires full locked axles (ARB)
Rear 4 - link coil spring suspension. Front still not sure what to do.

I know this is going to take a few years to get to the target..

If the auto isnt to big a issue you could go with a ford T18 or np 435 and then a gm 205.I think ,but am not sure, that they can be mated together.The ford 435 is dirt cheap and easily put behind a 258.

No Jeepney hehe

Hi

No she will not be a jeepney and I have a problem seeing a Isuzu diesel in my Cherokee...does not feel right. Yes I want an automatic.



Presently on Dana 44 axles, the tires are way too big for this setup just wanted to see where she stands. (Can't reach the oil stick anymore )

These are waiting for the drive train.


My baby's; Pajero 2.8 + M416 + Cherokee

Lars, send me a Kia KM450 with 12 foot bed (drivetrain and box not needed, but a good cab would be nice!) and I'll send you an AW4/NP208 combo along with the EFI to hook up to that 4.2L.


Actually, I'm selling the NP208J along with a Dana 300 clocking ring and AX-15 for $450 if someone comes up with the money soon.

Smile Kia KM450

Hi Jim


Hmm nice M715 copy have not seen on here but let me check just interest what a complete unit would cost.




http://www.angelfire.com/nb2/jeeppickups/Kia.html

Just did a quick glance on the linked page, a lot of Jeep info.


Anyhow on Thursday I am going to see my parts supplier to see if we can bolt together a TH400+NP205 combo.

Turbo hydramatic 400,thats what I was just about to suggest.over there in the Phillipines you are not going to see much highway speed.so there is not too much call for the overdrive especially with those tall tires.Stateside price on that automatic will be several hundred dollars less than automatic overdrives transmission.if you can find a chrysler 727 transmission laying about ,that would be no slouch either.plus you could use stock parts and do away with having to buy adaptors.

Tire rack.

Hi

The tire / jerry-can rack, is as per previous owner, from a Toyota LC which has been modified and lengthened.

It's heavy on the rear side panel. I have not checked if there is any internal supports. The lock is on the bumper and the hinges are on body.
I would suggest to make a bumper supported rack as it will be much stronger and will actually protect the body.

I will fix a picture in the morning.

See this thread for pix http://www.ifsja.org/forums/vb/showthread.php?t=68488


You are right the average distance travelled in one hour on National roads is about 45 KM and with 39.5" tires that will be fine

A few years back My Wife(who is from Leyte)and I travelled on that national highway from Samar to Manila. It was to say the least an Adventure.What always amazes me is that the rice farmers use the pavement to set out thier crops to dry and every body just drives around it.Then once you get into a town it sort of turns into the National sidewalk.Geography prevents the road from being anywhere near straight and the bus drivers are CONSTANTLY playing chicken with each other ,they think nothing of running each other of the road.The bus I was on got ran off the road twice in one trip!But that road is nothing. If you really want to get scared take the Victory liner (Philippine Equivalent of Greyhound) up to Baguio(the most beautiful place in the Philippines,7000 feet in altitude and the ONLY place in that country where an American doesnt sweat 24 hours a day.)That Road is more crooked than Al Sharpton's accountant,and more thrilling than any roller coaster ever devised,only because on a roller coaster you Know you arent going to die.

Baguio road Cherokee meets Victory Liner

Hi

Could not resist, a Cherokee and a Victory liner in same picture, Victory liner going to Baguio, Cherokee going home to Subic . Cherokee with breaks on one wheel only, not bad hehe it could be... oh no it could not be worse, but that we did not know then thanks Pam, Pam is my driver, good job Pam!
Sorry I can't print my wifes comment about how Pam looked after this trip... (Cebuano wife always speak their mind hmm.. not always in the most diplomatic way hehe.)


I have respect for Victory Liner, always give them way, they are doing a good job, can't blame the bus drivers from taking a smoking sedative now and then. Its a bit rough but one gets used to small margins hehe

You better take a new trip to PI and find the new Kamikaze pilots on motorbike...

WOW!they put up a guard rail guess too many San Miguel trucks went off the cliff there.The First time I rode that road there werent any.(1980).All I remember was no guard rails and VERY steep drop offs.A buddy of mine was in the Cubi Point flying club back then and we actually flew up to Baguio once.You dont realize in how many places that road has washed out until you see it from the air.We were able to get a cab driver for the day for a carton of marlboros and two bags of apples.Taking off from the Baguio airport is another adventure.Actually an act of faith.The end of the run way is a cliff.lots of praying and trust in the principles of aerodynamics and lift!In case you are wondering Lars I was in the USMC at the time ,once with VMA (AW) 533 ,The second Time with VMA (AW) 224 also known as the cheapskate squadron, Henry . PS ,In my opinion you are building the perfect vehicle for where you are in the world.Good luck and keep the faith.

in case i missed a post for this,forgive me if i repeat this....

if you want to stay auto get yourself a fsj th400, it will bolt right up to the 258(you wont need that adapter from a/a) then find a chevy th400/np205 setup and rebuild the jeep th400 with the chevy output shaft and np205(problem solved.)

Thumbs up Decision made: TH 400 + NP205

Hi

I finally made the decision it will be a Chevy TH400+NP205

No AMC TH400 available here. The TH400 will be overhauled before delivery any pointers for this.

There are some Chevy small/big block to be found, but thats for the future

So whats needed for controlling the TH400 - universal floor shifter? Kick-down cable? Me know nothing about this hehe...

Also need to add a oil cooler for the TH400, probably use a Pajero automatic oil cooler with an 10 inch fan, should be a easily available here.

I have no idea how the AMC 258 is in tropical climate does it need a oil cooler?

Well owing to the fact that your rig has been in the Philippine for twenty some years.I think it has survived the heat pretty well. i am of the opinion that straight sixes get rid of heat better than v 8s due to greater external surface area.you want to run a thermostat of course. i have owned amc six cylinders in the past that actually ran hotter when they stuck open.You will DEFINATELY want a transmission cooler, that is a MUST.and since you are the engineer in this I would also recommend a transmission temperature guage.Dont want to ruin your rebuilt th 400 because your Pajero cooler is undersized.I know how hot it gets there and how slow traffic moves these things do not bode well for trans temps.your biggest problem will probably be carbuertion.i knew a parish priest in Babatngon that had an old CJ that was his biggest problem.worn out old bbds do not respond well to prayers and it is a type of mixing bowl that the local mechanic over there is not too familiar with.
