Cliptfc's 97 Wrangler with 4.8L GM swap

I thought I would do a write up on my build. I was trying to make this build as budget friendly as possible. I've never done a swap before, and consider myself an average shade tree mechanic. Here's the day I bought the Wrangler last year, for $4200. She was a good running 4cyl with an auto transmission.

Here's the 4.8l, 4l60e transmission and the np231 transfer case mounted up. I used the Advance Adapters kit to mate the 4l60e to the np231 t-case.

I decided to use the Superior Radiator (out of Michigan) for cooling. I went with one that had the transmission cooler built in.

I didn't trust my welding ability enough to weld the new mounts in, so I trailered it over to a friend's place. I used the Advance mounts and they give you a tool to show you right where to weld them in.

Fitting the engine, transmission and tcase in. I put them in all in one drop....all mated up. I left the front grill off for the drop in.

The Advance kit required you do at least a 1" body lift. I went with the Zone 1.25" and it was a simple install. With the engine in, I realized it would need a suspension lift as well, as the power steering pulley was close to the front diff housing. It would have probably hit if it bottomed out. So keeping things on a budget, I went with Rough Country's 2.5" spring lift, with new shocks.


I realized the tires needed to hit the weight room after the body/suspension lift, so I had a set of 33x12.5x15 Buckshot Murder II's put on.

So I was trying to keep it budget friendly.... here's about 95% of the costs that were directly related to the swap.

Right now, my stock coolant, fuel, volt and oil pressure gauges work. I'm sure the speedometer will work, but I accidentally cut off and threw away the vss plug...waiting on a new one.

For the coolant, I reused the stock Jeep 3/8 not sensor with a ictbillet.com adapter into the rear of the passenger head. Didn't have to drill or anything, just installed it.


For the oil pressure, there was a plate above the oil filter I took off. It had a spot on the top that look like it was intended to be drilled and tapped for 1/8npt, so that's what I did. The Jeep oil pressure sensor screwed right in.
