I had been looking for a 2005-2006 TJ Rubicon for several months last summer and one that fit my criteria showed up on CL in September in western Idaho. I was fortunate to have a friend living near Pullman WA who could donate most of a day to inspect it (he owns a 2005 Rubicon). I purchased it. It is another that appears to have never been off roaded (there were no scratches on the diffs or skid plate but that deficiency has been fixed) and is rust free. It was a 1000 mile plus two stage road trip to retrieve it. After market bumpers, sliders, 3.5" lift of unknown origin, Bilstein shocks, American Racing wheels, Falken Wildpeak AT's, and relatively nice roof basket as received. It also came with the factory soft top, a bikini top, and half doors.

It got initiated into light combat several days after I got it home and then some relatively heavy combat on the McKelvey Lake trail a few days later.

Soooo, the roof rack was removed ASAP (it would not have survived the McKelvey Lake trip) and in between those trips I had time to get the ARB twin compressor that previously resided in POS (2012 JKUR) mounted under the hood. I also found a really nice used Zeon 10 for it. Some massaging of the front bumper is currently in progress to mount the winch. I managed to bend the drag link on that second trip so both the tie rod and drag link are now J. Currie items. Currently on the list of items needing addressed before summer are the upper control arm bushings-both front and rear, and some real tires (KM 3's). The Falken AT's are totally worthless in the rocks even aired down to 10 psi.

As for my Jeep history, it started with my late father's 47 CJ2A in the mid 50's when I could finally slide off the seat far enough to address those pedals on the floor. The only photo I found of that Willys in my parents slides, from 1957.

A couple years after that photo, my father traded the 2A off on a like new 57 Kaiser FC 150 which I proceeded to wheel in a lot of places it probably shouldn't have been. I purchased my first Jeep, a 68 CJ 5 which was new and titled as a 69, in 1969. That was followed by the purchase of a 55 CJ 3B three years later. I still have both the 68 and 55. I gave the FC to my brother last year. 1972 photo:

From 72 through 2012, the 3B was the go-to wheeler but it got supplemented in that latter year by a new JKUR.

I picked up another beater CJ three years back that left Toledo as an identical twin to the one I purchased new. Those two were built in consecutive months with all the same options, 225V6, 4.88 gears, and Empire Blue paint. The 225 in that rig is very tired but there is a good 305 has been languishing in the garage for a decade.

I wasn't the least bit impressed with the 3.6 in the JK. Maybe better than the 3.8 but that set a pretty low bar. The 4.0 is a lot better off road and doesn't come up too short on road. That said, both fall way short of a sbc, any Gen.
 
Awesome photos! I love it!

The 3.6 is riddled with problems. I hear more complaints about the JK and JL than I even care to mention. The 4.0 may have its weaknesses but it's a very durable engine and it's been around long enough that we know all of its common failure points.

BTW, got your letter in the mail the other day! I was going to ask you to see photos but you beat me too it. Those are some really cool memories you've got there and wonderful photos to say the least.

JK's in general are riddled with problems. I had a Christmas tree light display on the dash with 8 miles on the odometer. It didn't get any better. It was back on warranty 23 times, the service manager stopped writing it up for some reason. Only two of those were mechanical, rear axle seals and a NSG370 that wouldn't stay in gear. Then the left side head issue, the funky oil cooler, plastic thermostat, PS that couldn't hack rocks (no doubt shared with the TJ), tinfoil axle brackets and tubes, fuel tank light abrasion shield-maybe to avoid the stare of rocks? But what killed it for me was the electronics which eventually rendered it something I wasn't going to chance in the sticks and apparently unfixable. The pins in that wire harness were apart so many times that just that was becoming a potential problem.

Your story parallels that of so many JK owners I've spoken to. Yes, the 3.6 has more power and when it's running it's very nice to drive. However, I wouldn't trust a JK off the beaten path where I needed something reliable. They (just like every other new Jeep) are poorly designed pieces of junk full of electrical issues and so on. I have yet to meet a single person who has kept their JK for any extended period of time.

That's my other problem with modern vehicles, too many electronics. When you start having to rely on that many electronics it just becomes one more point of failure. The TJ isn't terrible since it only has one computer and a handful of sensors. That isn't the case though with the JK and it gets even worst with the JL.

That's why I bought a 1973 Chevy K10. Simple as hell and so few wires that if it broke down on me I know I could fix just about anything on it myself pretty easily. In addition, it's just not fun to work on these new vehicles. Working on older vehicles was fun because you didn't need a laptop (or phone) to diagnose them. You could figure it out very easily by just looking for air, fuel, and spark. On the newer vehicles if one sensor or computer fails the whole thing is inoperable.

I think my dream swap would be a TJ with a 350 SBC. I'd swap out the carbs for a Holley Sniper (basic fuel injection) and call it a day.

The TJ for what it's worth really is the last Wrangler worth owning.

Yep. My wheeling buddy from the mid 70's to the present traded his sbc powered FJ40 off for a spanky new 93XJ and I thought he was totally crazy. 320+k miles later changed my mind on that. He finally found a nice 97XJ several years back to repeat the process with. 4.0 forever. I have no intention of swapping that out of the TJ even though there are a half dozen available sbc's sitting here.

My problem with the XJ has always been the unibody. I've owned enough of them to know that if you take the off road and flex them the frame will warp, twist, and crack. You can get chassis stiffeners to remedy the issue to some degree, but it still doesn't beat a body on frame of course.

I like the 4.0 for sure but I'm a SBC 350 guy through-and-through. Maybe it's the sound of that V8 :LOL:

up the ante
The bucket list engine currently under the hood of the 3B, perfectly square, 4.125" x 4.125"

Wow! That's one hell of a nice looking engine. I'll bet that'll put out some power.

I put that engine together using Comp Cams Dyno Sim 5 specifically for low end torque, an interesting exercise being it was diametrically opposite to the usual scenario. I also wanted to avoid custom parts to the maximum extent possible for obvious reasons. The pistons and camshaft ended up the only custom pieces. The program rear wheel outputs are 407 hp and 481 ft-lbs. More to the point 351 ft-lbs of that torque is present at 1000 rpm. I have ProFlo4 on that and a different induction not based on the single plane Victor JR would make a big improvement in bottom end torque. A high flow TPI system could produce more than an additional 50 ft-lbs at 1000 rpm. Alas there are limited (as in no) off-the-shelf options there but I'm totally sold on port induction for a low rpm engine, none of the usual wet manifold low rpm fuel distribution issues. I did have some correspondence with Wilson about building a TPI system for it but that was really going to get into mega $. I can probably break enough stuff the way it is.

Back to reality, the 381 sbc that previously resided in my 3B from about 1981 through the next 35 years worked VERY well and I put that one together using entirely GM parts as there were no 383 kits at that time. Not much more expense than building a 350 and definitely worth the effort. Essentially the 400 torque without the 400 pitfalls and very close to the 350 economy. Highly recommended for Jeep power if sticking with Gen I. Plenty sufficient to put a really big shit eating grin on ones face.

I can't argue I'm not elderly, yesterday was #81. That said, I still really like playing with Gen I sbc's as I have been for the past 6 decades. Parts interchangeability is unsurpassed in any other platform and those parts are both more plentiful and cheaper, not to mention the aftermarket support now rivaled only by Gen III+. The Gen I sbc remains the best bang for the buck that exists.

Yep, that's why I like them so much.

Easy as hell to work on and finding parts is easy as can be. They're a great engine and they sound awesome to!

Absolutely love that red Willys Jeep in the photo!
