Yea hopefully the pitman arm will help you. What suspension do you have? I have a drop pitman arm and a 4 inch superlift on my sbc powered cj and I havent noticed any pulling so hopefully that will help you. Then again my lift is fairly stiff so that may be different.

Mine is a BDS 3.5" Lift. The drop Pitman Arm solved the problem.

Now to fix the wheel hop/axle wrap issue without sacrificing ground clearance. I've got a Ford 8.8 and the install kit from Know Where 2 Jeep. I need to figure out what to use that way I can build it up all at once.

Since my rear springs are fairly soft, I get quite a bit of squat on launch.

I've been looking at the MORE setup, but since I'm not using the stock skid plate I think I'm going to have to do a DIY. (The MORE will be to short)

I'm going to need to do this because the wife is a leadfoot. She's the original reason for this swap. After she broke a trans mount and an engine mount on the old 4 banger trying to climb a hill (unsuccessfully), she said the Jeep needed more power.

The last thing I need is for her to break a u-joint or the straps.

That is awesome yea you can also throw a drive line loop into the design just in case. Have u been able to drive it much? Figure out mpg at all?

Yes, I've put a few hundred miles on it.

It's nice to be able to run on the freeway at 70 MPH and not have the pedal mashed to the floor.

I haven't thought to check mileage since it's not my daily driver. Plus driving it is so fun that I'd feed it no mater how bad mileage was.

I guess I'm conditioned to expect that fun things use lots of gas since nothing can be worse than an old boat I owned. The twin 502 BBC's used about 125 gallons per hour at WOT and it had a 265 gallon tank. It also required 91 octane. Talk about pain at the pump.

I know that boats can burn through the fuel, i know our little 350 in the ski centurion uses a fair about but nothing close to that, that is insane amount of fuel.

I know your not building the jeep for mpg, just curious as to how it was doing, I am thinking of swapping the sbc out for a lq4 that I recently got and was wondering how yours was doing. I only manage about 9mpg with mine, i am sure yours is doing better than that.

You should try to post up some other photos/videos if you have them when its convenient.

Sorry for the delay in getting more pics up. To busy driving the Jeep.

Just a quick note to say to anyone contemplating this swap that this was the best mod I've ever done to a vehicle.

Yesterday it was 94 degrees here and 78% humidity and a friend called me in a panic because he needed to move his 1968 Cougar. I hooked up a dolly to the jeep and towed the car 15 miles. Temp stayed around 205 degrees in the stop and go traffic.

I've also used it to tow my ski boat on the freeway at 70 mph on 90 degree days and the temp stayed at around 210.

Here's a shot of me climbing the retaining walls at my house.

I second the idea of the best swap for a Jeep. Mine has been totally reliable summer and winter. You can drive it like stocker or smoke some of the local hot rod boys. It's all good!

Is that not one of the best swaps yet for a LS motor. Scared yourself or others yet?

Not scared yet, but then I am pretty conservative.

We're having a blast with it.

I just took my wife and daughter down to Woodward Ave to check out the pre-cruise people that were down there.

Default On the dunes.

Earlier this week we took the Jeep to the Silver Lake Sand Dunes to see how it performs. Keep in mind that the trip to the dunes last year is what started this project because the Jeep could not climb "Test Hill" with the stock 4 cylinder.

Here's the hill:



Just for kicks I decided to leave the transfercase in 4HI and see how it would do. Since there are a bunch of moguls at the bottom of the hill and I had my daughter and a day's worth of supplies I didn't want flying out, I eased up to the base of the hill (almost lined up with the sign) and then hit the gas.

Here's a shot as I was headed up:



About 3/4 of the way up the tires started to break traction. This was where the little 4 banger was not able to keep up but since the 5.3 has enough power to go up in 4 HI all I did was add more throttle. The next thing I knew I was on top. It was at that moment all of the work paid off.

FWIW, I left the shifter in 2 and did not have to floor it to get up the hill. As a matter of fact I don't think I went above 3/4 throttle all day.

Just in case you are still not impressed how about this....

Problem: 8000 lb Crewcab Diesel Dually buried up to the frame on top of a dune.

Solution: 3000 lb Jeep with 300+HP and a towstrap.

The hard part was that all of the work was on a hill. After breaking the towstrap twice the dually popped out and after we got everything unhooked he was able to back down the hill.

Default Some more eye candy

My daughter and helper on this project:



At the top of test hill with one of the "Big Dogs" of the day. International Truck was testing a couple of their armored military vehicles that day. It's an up level variant of the MXT (I believe it's called the Husky) for the British Army but is much more stout and more capable off road than the base MXT. They had what I would call a base MXT (smaller tires/axels) there but he did not get to the top of test hill. I don't know if the driver was conservative or what but he took a couple of runs at it and gave up.









My new favorite pic:
