I bought my current 84 CJ7 back in 2004. It had an AMC 360 and a T176 at the time. Here it was not long after I bought it:
The 360 didn't last long, after it bit the dust I built a fairly healthy 383 stroker for it.
After I was deployed to Iraq, I started collecting parts to swap in some full widths. Here it was on Corporate 10 front and 14 bolt FF rear, along with some 40/17 Ground Hawgs.
While I was stationed in North Carolina, I quickly found that I LOVE mud racing. But the class I had to run in what whipping me up and down the track...so I beefed up the 383 so that it wasn't really streetable anymore...I went through a couple different transmissions, and so far the latest one, the TH350 that's in it now, has held on for the ride. It's got a TCI reverse manual valve body in it, and a 4000 RPM stall torque converter. The 383 also started getting old and tired, so I found a 400 block, and built a sweet little 402. I won't bore you to tears with all the engine build pics, but it's got a steel crank, forged 6" rods and forged TRW pistons with TRW ceramic coted moly rings.
It's got a pretty decent solid cam in it, .530ish lift and 250 duration @.050.
I'm currently building a new carb for it, a Holley HP 850 double pumper.
For body work, I replaced both rockers since they were rusted and repaired badly by (I assume) the previous owner...or whoever had it before him. After that, I hacked a hole in my hood and grafted on a cool "little" hood scoop, then sprayed it with Gun Metal Grey Metallic.
The Jeep was still too heavy, so I swapped in some 1/2 tons, a 10 bolt front and 12 bolt rear, with 4.56 gears. It's currently riding on 38.5x11 Boggers, too. I'm looking for a pair of 38.5x15 or 39.5x18 Boggers to make some rear cuts from, if anyone knows where I can find them for "cheap."
While it's been down for the winter, I started modifying my headers to tune them to this engine, since they were waaaay too short. I won't show pics of the whole build, unless anyones interested...but here's a couple.
During: (mocking up to measure for next set of bends)
After: (They're painted with VHT black header paint now)
Those are 1 3/4" primaries into 3 1/2" collectors.
And here's my favorite pic, hauling booty through a mud pit
And finally...some action pics:

This was "only" a 6 second run...that 383 was getting old.
Obviously, as we all know, no Jeep build is EVER done, so we'll have more pics/progress soon!
