How Far, How Fast?

For those out there with stock, non-rebuilt 360s, I'm just wondering how far you guys drive on the highway at one time, and how fast you go on average? I've got an 87 with 132K miles on it, which runs well, doesn't burn oil (prefers to just leave a bit in every parking spot ). I've gotten it up to 70 MPH with no issues, but have only done this for 20-30 mins at a time max traveling locally.

Do you guys travel on highways for extended periods at this speed (like 4-5 hours, cross country driving)? I'm trying to build up the guts to drive mine to the Outer Banks, but if traveling at 70 MPH isn't really an option for 4 hours, the drive would take too long to justify taking the Jeep. And yes, I understand that as with any older vehicle, it's hard to know for sure that it won't just up and die - I'm just talking about "best case scenarios".

Appreciate any thoughts.

Depends if ur cooling and engine.is up to snuff, I drive 5 he's 75.80 mph no problem passing semis Audi's and escalades. These Jeeps are a dream to ride in on the interstate, a little louder than a new car inside tho

It's had a cooling system flush, all bodily fluids changed, etc. and doesn't seem to run hot (based on stock temp gauge) or overheat. Guess the only way to find out it to try...thanks!

I can remember dad running the old cherokee with the 360 from Northern Mi to South East Kentucky with the speedometer needle bouncing off the peg a couple times! Never had problems with that old Jeep. She fired up a purred the day he took it to the scrap yard! Body rotted out of her, being from Michigan. Then again we are talking about the mid 90's so the jeep would have been 10 years old or so. So I would say as long as your jeep is in good mechanical condition, you shouldn't have any problems with it! Drive it like you stole it.

Mine is my weekly driver to the airport and back. I drive it all over N. Michigan and to the lower part of the Mitten as well. My speedo isn't working over 50mph but on the interstate I use my phone speedo and set the cruise at 75mph. I regularly pass if needed. I have NEVER seen my stock temp guage go over the top most of the "Blue" temp area. It has gone a smidge into the white bar in the top of the blue when it was 80* outside.

I've never had an issue.

It is pretty damn funny to pass people in this beast on the highway.

I've driven mine FARRRR....

I actually drove mine fully loaded, stock all the way to northern Texas from Harrisburg, PA no issue. Mine was pretty much stock and loaded with all my things for tech school for the military. I then drove it all through tech school for 9 months, and then to Little Rock, Arkansas. Then finished up driving to Indiana, back to PA. I would drive mostly 8 hour days with some breaks for gas...I mean these are 2 and a half ton pieces of metal. I was cruising around 65 or so. Every stop I would just double check all the fluids and whatnot. Make it an adventure haha. Everytime i drive it long distance it usually is. Not to mention that youll get the celebrity treatment when you make it to the outer banks. Hell, I was gonna drive mine to Florida eventually to take it on the beach.

I don't hesitate taking my 90 down the hwy for extended trips. I do carry a toolbox though.
I have a little shimmy that floats around 65-75, but I can usually find a smooth spot. I have had it up to 90 for a couple mile, something I thought I would never do.
Watch your temp, Watch your oil pressure. These rigs were made to run at 70mph.

What am I missing? I'm about to pick up a 86 wagoneer and couldn't think of a reason not to run at highway speeds unless there ends up being a mechanical issue. I live in Wake county and can't wait for the trips to OBX for some camping and fishing.

I got an '82 recently with a 401 I can't afford to feed so it's being swapped out for a 4.0L (selling the running 401 for $750)

I'm probably being overly cautious, but just wanting to know what others have experienced as we're not dealing with modern technology vehicles here, and just based on their age "stuff" can just happen. I have every confidence that the truck would make it the distance, but was primarily just wondering about running at speed over time. This three speed tranny just seems to really need an OD gear to really run at hwy speeds in my opinion, compared to other older cars that I've owned over time. I'm sure my worries are unfounded.

Take mine everywhere with the family. 600mile weekends are fairly common
Take a small tool bag and there is hardly anything you can't fix. Keep red/black wire, tape, some screws and you should be good.
Most parts are available at pep boys, advance or autozone.
I do check my fluids once a week and have replaced things that may or have gone bad.
Spark plugs, cap,rotor, spark plug wires, ignition box, water pump, belts etc. I replaced my battery last week. It was from feb 2000. 13 1/2 years old.

In the past year it's had new Spark plugs, cap,rotor, spark plug wires, belts, starter, starter solenoid, neutral safety switch, radiator flush, tranny fluid, 4" BDS Lift (springs shocks bushings), steering stabilizer, and new 31x10.5x15 tires. Brakes are good according to my shop. 4x4 works without issue, cruise doesn't (don't care as i don't use it anyway). I have a full tool box in the back, just in case (as well as a AAA membership ). Gonna give it a shot around Thanksgiving - my wife will follow in another vehicle just in case (have to take 2 regardless).
