1984 J20

[Leehi417]

i recently sold my comanche ( there wasnt much left of the comanche... tires suspension and body ) for $100

and found my new toy a 1984 Jeep J-20 3/4 Pickup for $400. the guy i bought it off of was moving and needed

it out of his yard asap. he wanted $750 but i got him down to $400. its been sitting for 8 years but is in real good

condition surface rust here and there but its a beauty.

 

Specs:

 

5.9L AMC 360

Bored .30

Hedman Headers

aftermarket cam

Future Plans:

 

1. Get it running good and street worthy

2. Paint it something other then Red

4. 1'' body

5. 37'' tires

i pulled the plugs and wires,

changed the oil

got a new ignition coil

new battery cables

i sprayed inside the spark plug holes

 

 

i turned the ignition and she turned over !.

one step down at least i know the starters good

 

next i plan on getting new plugs wires and distributor cap

along with belts a new radiator and hoses.

 

then i try firing her up and try to bring this old

lady back to life.

work slowed down and I'm running out of money :headpop:

so i have to hold off on a lot of the things i wanna do but

the other day i got the new plugs wires and distributor cap.

drained the old fuel out of the tank.

 

next plans are to get new belts

radiator and hoses.

 

does anyone have know a really good fuel cleaner to break up

the crap that might be sitting in my fuel tank?

My J-20 pulled an overloaded big U-Hual from Utah to Maine in 1985 and got 15-18 mpg all of the way.

 

Great truck and when driven in Boston "rotaries" (sort of like "Rollerderby" with cars) the turbo Saabs could not get out of my way fast enough.

 

To clean and re-seal your fuel tank, I would suggest going here.....

Buy a quart of Tank sealer, a gallon of Marine Clean, and a gallon of Metal Ready. Follow these directions....

Welcome to "the dark side". I own a 76 J-10. I bought it in October 2000. Put alot of blood, sweat & money into it.....I still love it....even though it's been off the road (not in a good way) for a couple of years. That's why I bought my Comanche, that and a real good price. The J-10 will come back to life!!!!! If you don't know about this site, check it out asap; http://www.ifsja.org/forums/vb/ I can't say how much I've learned from them. I'm on that site also. Good luck my friend, look forward to seeing posts from you. Jim

Now I have a little more time to post. fsj-list@yahoogroups.com[/email] (there are some regional lists as well like

 

My '83 J10 is a longbox with 4.2L that I stuffed an AW4 into along with the NP208J (I was going to put the J20 axles from my '73 J4000 into it) I was going to use it to tow my 5th wheel, but I got a shortbox '76 J10 with J20 axles. I put the 304 from my '73 (that I pulled from my '77 AMX) into it with a 727 and Dodge Ramcharger NP208D (mirror image of the Jeep one so I don't have to change axles) That will do the job nicely (and I can sell off the '81 Chev C20 with 454 I currently use for this job while the price of gas is still down)

[Leehi417]

i fired the truck up today, she lives again. added some fuel cleaner and fuel

and she fired up after the third try. after sitting for 8 years it good to know

she works. works still slow so i can't do the things i wana do but ill keep

you updated when something happens. she sounded nasty, if i can find my

video camera ill video her running for a couple seconds.

Those autolite carbs are not the greatest set ups but are pretty easy to rebuild and can be made to run decent. Be sure to set the float level correctly and to use compressed air to blow out the passages.

 

They tend to "mung up" when they are fed dead old rusty gas.

 

My 77 J-20 had a T-18 in it.

[JeepcoMJ]

gah!

 

I almost ended up with this 11k mile gem...

 

unfortunately my deal fell through. but, he's got an M715 that's rust free to sell me for $1200...comes with a nice swivel turret too :D

[Leehi417]

i took this video with my digital camera

but here it is.
