Youngjeeprs build take 2

Well over the last 5 years I have built my 88 YJ from stock to SOA and 3" front stretch with a 8.8 in the rear, a D30 up front locked with chromolys, and a 350 under the hood with a th400 behind that. After having the 350 in the jeep for almost 3 years I got tired of hunting for someone to test it for safety/emissions every year so after my boss gave me his 93 XJ I Decided it was time to build a 280hp/330tq 4.7 stroker to replace the 350. Im also planning to stretch the rear 5", build a D60 for the front, 14 bolt for the rear, and build a full cage. The first part of this build will be the motor build/swap and temporary cage. I plan on having this done by the begining of march, so things will be moving fairly quick. I hope you guys enjoy my build, I know im going to. if you have any sugestions,comments, or questions feel free to ask.

Ill post some pictures from my last build thread to get everyone up to speed.
What I started with

Then came the SOA/8.8 swap. This picture is from before my springs setled but they are stock springs.

Then came a couple different sets of tires and many broken parts, and finally the 350 swap.

Then came the front 3" stretch.


After I did the front stretch I wheeled it a couple times but had some vapor lock issues with the 350 so it sat till I could get to fixing the problem and while it sat I got the XJ so I started planning the 4.7 build/swap.

Here is the XJ


After 4 hours and a few beers the motor/trans/tcase was pulled.

Today I uninstalled the new seats and tore out the dash. Then I figured out what I need to do with my wiring harnesses so tomorrow I'll re pin the bulkhead and strip all unnecessary wires. I cant wait to get this thing back on the trails!

Today I ordered my pistons, cam, valve springs, timing gears/chain, head gasket, fuel pressure regulator, injectors, and my front cage kit. Tomorrow I'll drop the block and head off at the machine shop to be cleaned bored decked and ported. This is going to be a busy 29 days.

I am. My pistons came today and I dropped them off at the machine shop so I'll have my motor back in a week or so. Some time this week I'm going to go pick up another YJ frame to cut the motor mounts off of. The only part I'm waiting on that is important is my fuel pressure regulator.

Well went and talked to the machine shop today and my motor will be assembled (short block for balancing) by Tuesday or Wednesday. Now the only parts I am waiting on our my brown dog mounts, header, muffler, cat, and my btf front cage kit. Today I got my 50" light bar and fuel pressure regulator.



The tall trees in the background are 200-250yards away. Also the light bar was only about 4' off the ground so it will be even better once it is mounted on the jeep.

I've been thinking about getting a light bar I just have to get out night wheelin more often.

Hope your engine comes together smoothly. Think there will be enough time to chase down the bugs before the 12th?

Most definitely. I know all the sensors/ accessories are good. I drove the Cherokee I pulled the motor/trams out of home and it ran great especially for having 285k miles. The only bugs I'm worried about are in the wiring harness. But even if I have to redo the wiring harness it only takes 5 wires to run. So if I have to I can rig something up till I get back from Moab.
