The Result

by Steve on August 26, 2007

Things have been quiet around the Shed lately. I’ve been rather consumed (wife says obsessed) with completing the second overhaul on the old CJ. My personal time spent tinkering down in the garage combined with the roll-out of a new Customer Relationship Management (CRM) software program at work has severely limited all other activity. Now that the Jeep is finished (do you ever really “finish” one?) I’ll return to regularly scheduled posting. In my own defense I did have to get the wife’s parking slot in the garage turned back over. More room to work on her side you see. Causes a little friction but it does keep the procrastinating to a minimum!

Here you have it:

To complicate the process I decided to do a major upgrade under the hood. The current configuration includes a 4.0 liter cylinder head atop the original 258 straight six. But wait, you ask, why put a 4.0 head on a 4.2 block? Bigger valves and much better design characteristics for to yield better flow. Power, grasshopper, more power. Bolted to that free-breathing head is a complete Mopar fuel injection system. She’s now a CARB-legal stump pulling powerhouse with better gas mileage numbers to boot. The old upgrade gave her a little boost in performance but it was barely detectable. This make-over was immediately apparent on the test drive.

Now to call the insurance company and discuss stated value coverage as opposed to the current book value on a 1986 Jeep CJ-7.

Congratulations on the completion!

Looks fantastic, and what`s really impressive is the work you did on the engine…what a difference!

What do Moose and his brothers think of the new look? By the way, will he soon be returning from his hiatus/vacation/sabbatical? Here`s hoping.

Looking good Steve.

What James really wanted to say was, “Thank God he got it back together” considering he’s signed on as co-driver, navigator, spotter, and general go-fer on the upcoming expedition to SW Colorado in a few weeks. 😉

Good work, but I’m going to bet, lots of fun. Did you keep the old electrical system? They make lots of aftermarket elec. kits that are nice.

I see you have a warm air intake. Thats good and if you get in much water, will keep it out of the engine. But where I live, a cold air intake is much better. Even with temps running around 100 in the summer, giving a car a little cooler outside air helps in many ways here. We don’t have a problem with very much rain, altho we have had more this year than in a long, long time.

Congrats. Yea, it’s never going to be finished and explaining that to the wife will be near on impossible.

Good job.

Thanks!

Basically the Jeep now has two wiring harnesses: the remainder of the original which powers the dash, lights, etc. and a new seperate one for the computer (gasp!), fuel injection, and distributor (controlled by the computer – yuk). Obviously certain concessions were made in order to gain the benefits of semi-modern technology. The good news is being a MOPAR kit it’s all off the shelf stuff from a ’94-’95.

I’m not real happy with the air intake that came with the conversion kit and will eventually replace it with a cold air kit. The current configuration leaves the intake exposed to the heat of the engine and is in a direct line with the fan. That only poses a problem with deep water/mud where the fan becomes a rotating shovel but her days of diving into anything that deep are over unless it’s absolutely necessary!
