LM4 5.3L and 4L60E swap into 2004 LJ

Locktite probably isn't going to work, you use heat to remove red locktite. You might need distorted thread nuts if new bolts doesn't fix it... I might would even try to tighten them when they are hot (expanded) and let them cool.
I need to try this on the ferd. She gots a little ticky ticky

I have a clip on the tailgate to fold the antenna down when I drive it to work. It hits every one of those horizontal beams, and if it gets to swinging and hits one when its forward I'm afraid it would break it.

This garage clearance is 6'8". The white truck radio antenna hit every sign and it was only a couple inches above the cab.

We worked a couple hours today cleaning up wiring and getting everything connected.

Tripp cut a plastic panel that mounts where the Jeep ecu went. We put a positive and negative bus bar on the panel and ran most items to that. There's still a couple things to add and I've ordered some big split loom to combine some of the runs.

First refuel, about 12.5 mpg on the first tank and I was never easy on it. Pretty sure its rich too. Taking it easy and after a tune, I see no reason why it wouldn't exceed the 4.0 mileage of 14.5.

The stock jeep radiator cap was bad and wasnt building pressure. I got a new cap, drove it a little, then drained the straight water Sunday morning and put in coolant. Sunday night there's a puddle under it. New cap, system built pressure, water pump leaking. What's another 100 bucks at this point... :rolleyes:

Wasn't a bad job, but I looked at that motor sitting on the pallet so many times thinking I should have changed thermostat, water pump, etc just to be safe. I didn't, and now I've changed both within the first 200 miles.

Took about 2 hours start to finish working slow and cleaning things up. Not adding it to the log since it's more of a maintenance thing, not conversion.
