Anyone know about 1966 J3000 PUs?

[jfalken]

I have listed my 1977 J10 in the For Sale area due to emissions problems. I am now looking for an older truck to avoid the whole thing. I may have a line on a solid 66 J3000, but don't much about them. This one is supposedly a 6cyl with a 3 speed stick. What are these like? Will it be a royal PITA to work on or find parts for? What do you guys think. Obviously, I need to get rid of the 77 first, but Hopefully it will go somewhat quick. Thanks for your help. Man if I wanted an old Chevy or Ford, I could have my pick, but these things are like Chicken teeth. :D

ok, i have 2 trucks... 1 a 63, and a 64... has the 230(232) OHC .... its actually a good motor, just that its underpowered.... but good low end tourqe........

mine have been good, but i droped in chevy motors and trannys.... but kept the dana20 Tcase..

Just drive it first... look for leaks.... ect, normal things that u do when u buy things....

[Green Giant]

Nope.......don't know a thing about 'em.

[Kenall]

well if its a REEL 66, then it SHOOD have the 232 I6 with T14 tranny. (very good) but if its just a late registrated 65, (not so good) it cood have the 230. look for the word 'tornado' on the valve cover.

[jfalken]

Is tornado the very good or not so good? Also is it possible to get the normal maintenance type stuff for this old of a Jeep? I realize any body parts will be catch as catch can, but I do like to know I can get gaskets/filters/seals and whatnot when needed. Thanks for your replies.

The Tornado is a major accomplishment of the 60's automotive industry :D

And you get to say that your jeep has a Hemi tongue.gif

A J3000 (in 1966) designated the truck as the long wheelbase with a V8. The 6cyl would have been a J300.
According to the '66 TSM three engines were offered:
J300 230 Tornado 6cyl
J300 232 High Torque 6cyl
J3000 327 Vigilante V8

The 230 model came with the more antiquidated bell crank steering system. The other two had the saginaw steering box with the 232 having a hydraulic ram assist for power steering as an option and the 327 had a power hydraulic steering box.
If the truck really is a J3000 it would most likely have a T98 four speed or a TH400 auto. Most parts are obtainable, but 327 parts are getting scarcer. We can set you up with some good links to help.
I've got a '66 J200, that's the shortbed 6cyl, but it's closer to a one ton now with a 401.

Oh yeah, all three engines were designed for leaded gas so guess what... they will need the head/s pulled and bronze valve guides installed along with hardened valve seats.

Well, if you had the money you could do like mine and just snag that '66, swap (with a little fab work) the titled '66 truck or even just the cab onto your '77 frame and running gear... drive it back in for emmissions and tell 'em the '66 runs cleaner now that you put a newer engine in it. Unless your State has a max emmisions amount regardless of year of the vehicle.

umm.. iv just turned 100,000 miles on my tornado(64 Wagoneer) ,Iv been running some 2 stroke oil in the gass to lube the valves and rings... for a year now... this new gass hasent killed it yet!!!!

and i do belive that the 232, and the 230 was the same motor, just a slightly diferent stroke length....( could be wrong.. wouldnt be the first, or the last time)

[Mikel]

Mike,
The 232 is the grandaddy of the 258, both AMC engines. The 230 is an overhead cam Kaiser engine.

Yup!
BTW...it could have a T18a behind the 327 also. At least mine does.
And yes it's factory.

QB]You can get by like that, I get tired of adding crap to the fuel all the time. What does that do for your emissions, or they probably don't test you in Eastern WA being a '64 huh?

It does it automatically! Look at it as a "feature".
I also run premium fuel in mine; I've never been able to get rid of the spark-knock other wise.

Really.. i dont have any knock...
And i run a msd6a on her too....

Only oil i notice is on the ground.... got a cap and rotor and a new valve cover gasket( yesterday) ... lets see if the oil spots diminish (they will never go away)

However, this combo is unlike the later 360/T18a combos that require the 4 or 5" spacer between the bell and tranny. The one I own, has an approx. 1" spacer between the two. If thats what your refering to.

I have a '64 J-300, changed motor; now have a 350 4bolt main chevy attached to the T-90 tranny/ D-20 T-case. Rewired the entire truck to include installing a switch with a L.E.D. ( so I remember to turn it off) for the back ups, as there is no switch on my tranny. Drive line parts are fairly available up here in alaska, body parts are not rare, but not as common. These are great trucks, even better with a chevy powerplant.

[ColeTrickle]

Yup, thats what I was thinking too. But I have heard from Scotty and others that there were three sizes on those T18 inputs...

[Rande]

Haven't seenany info about the axles. What would it have?

[ColeTrickle]

Here's the specs on mine.
327/T18a/D20/D44 closed knuckle front with a D60-2 semi-floating rear. 5X5.5" lug pattern.
