I'm pretty confident in my O2 sensor wiring at this point. I also went through and checked for any vacuum leaks last night. I wasn't able to find anything in the few places that people mentioned to look. At this point I'm leaning towards buying a new MAF sensor.

There's a fitting that you buy from the dealer...it's in the pirate 5.3 thread and I'm just too lazy to look it up for you right now. That just pushes into the intake. I then bought some 1/2" heater hose with a molded 90 degree elbow from napa.

I noticed that trend among Jeep owners. Once they complete a job, they don't want to help others. I have actually asked some why they do that and the reply I get it "it has been done to me".

Well, maybe someone else will chime in and post up the cost for others. That is why we come to this forum right? To get help and help others

I'm still here and I'm willing to help. What do you need?

This is the result though:

I started another thread for that...not sure if I posted it in this one, too.

This is just the engine swap cost...not the cost for the whole thing...and I probably have another $100-$200 tied up into minor items after I stopped keeping track. I did a pretty good job of keeping track through 90% of it though:

Was it worth the power. I hear some say the stroker wasn't worth it. While others say it was. I am sure it has more than the 4.0l 188hp vs 300hp but how much did you notice?

It's a significant difference over any other jeep that I have driven. I would like to say that it is worth it, but here I am selling it, so what do I know? I think if you go into knowing that you are going to spend that kind of money, then you'll enjoy every minute of it.

I started working on a stroker a couple of years and I think I could have finished it with about $1500. $4k+ vs $1500....hmmm. I can't say I have driven a rig with a stroker in it though.

My catch 22 is I want a automatic now. Back went down hill. To put a chevy trans up to a 4.0l is $1000 in just adapters. Figured, getting a 5.3l and trans would cost less than that. Sounds like I am right. Just, there is other costs involved.

What was wrong that caused the rich condition? Is the stock radiator keeping it cool? It's nice to see you reach the finish line, I still have a long way to go.....

I ended up rewiring the O2 sensor part of the harness. I put the proper end on it and soldered it this time. That worked out well.

The stock radiator has been keeping it cool...even on some 90 degree days.

I've kind of fell of the planet but am happy to help. I've been busy and haven't been on the forum. I'm happy to see you have it running!
I would estimate my 6.0 swap close to $5000. That's a used motor, 4L60E, 231C/J tranfer case, all new autometer gauges, computer, wire harness, motor mounts, fuel pump, and a reluctor ring with adapter for the speedo. Thats $0 in labor. It's anpricey swap, but it's sure fun! A stroker 4.7 won't put out near that much power without serious reliability/longevity issues.
