Wranger V8 swap info..

LS all the way! There happens to be a member on here who can help you out with the harness! @Wwildman

4.8/5.3 are cheaper to buy initially than a 6.0. Only difference is their stroke (crank and rods), pistons, and heads. 4.8s have longer rods and flat top pistons. Both make great power. They're all the same size though. If you want a 5 speed, you can run an NV3500 or NV4500 and whatever 32 spline GM transfer case you want. I've got an NV4500 with an NP205 (passenger's drop) and an NV3500 with an NP241 (driver's drop). The 3500 is actually fairly stout, albeit it, not as strong as an NV4500. I have a strong 6.0 in my Silverado with an NV3500 behind it. It's SAS'd with 37s and it's been a trooper.

The possibilities are endless!
 
I vote for a 5.0 from an early 90s mustang. Able to run off just a few wires with the stock mustang harness then if you throw on an explorer intake, cam and exhaust you'll be at 5.3 power but in a smaller more simple package. That's the swap my jeep is going to get someday, though I'm also already running a ford np435 so a ford motor makes life easier for me. With that said any v8 swap in a tj or yj is illegal per EPA regulations. EPA only allows it if the engine was offered in the chassis and is the same year or newer.

My .02 on the subject,this time last year I was finishing up a LS swap in my wifes YJ usin a Jims perf harness.I was originally gonna use a TBI motor but couldn't find one w less than 200K and they were $650 or more for one.I got a lo mileage 5.3 w the ecm and harness for $800,harness mods and ecm reflash was $550.If you do a LS swap and don't get a donor vehicle make sure you get the gas pedal assembly if its drive by wire,mine was cable.Getting the gauges to work is a little tricky since the LS block has metric threads but they make parts to adapt the sensors over to work w the LS.For me its LS all the way,I have one waiting to go in a 68 pick up now.
 
For the LS swap, this helps a lot. Being able to use aftermarket style gauges makes it that much easier unless you adapt the harnesses and use factory gauges

Equus #9848 has all the metric adapters you'll need for gauges. It's about $10 for a pack of 5 different adapters.
yeah I bought some auto meter adapters but they weren't $10 :shaking: Im gonna have to change the temp gauge,it must not work w the sender.I ran it all summer on 260 and it never lost a drop of coolant and the infrared thermometer never read over 210.

There are two different types of senders. One is longer than the other. I'm not sure off the top of my head which type sender is for which type gauge. I think one is short sweep and one is long sweep. Mine is the longer type with two spade lugs on the end. It came with the Autometer Pro Comp Pro Dash that I'm using. The long senders won't fit through most of the adapters, but it does fit through the Equus.
