Howdy! Just wanted to drop a quick update that things are moving really slow but things are moving. The roof was painted last week and the body is ready to be painted however, the paint hasn't shown up yet. We have the black for the windows but the body needs to be painted first.

I've also had a set back with the A/C setup. The stock compressor is not compatible with Vintage Air. With the help of sonoraed (much appreciated), we've been working out details. I've called a number of places trying to find a compressor that mounts to the stock location but there's none. The issue with the stock compressor is that on the GenV motors, it's computer controlled, there's no clutch to activate. I called ICT Billet whose power steering pump kit I currently have and checked if they have a solution. They suggested I try their LS7 p/s kit with their GenV a/c kit. They sent me out the a/c kit and p/s brackets to check fitment. The head bolt pattern on the GenV might not match with the LS7 and the p/s bracket mount to the head. The other option is to go with a Kwik Performance kit that has both p/s and a/c. This is a new solution that wasn't available when I was searching for p/s. ICT has been great to work with and I'm hoping their kits will work.

Once the a/c and p/s is sorted, I'll work with sonoraed to finish up the details of the a/c system. Again, Ed, thanks for all the help!

With the Jeep in paint booth it's hard to keep moving forward right now but it gives me time to sort out other issues that might come up. I have found a floor shifter that will work with the 6L80 and I get to keep manual shifting. I've also got a cable t-case shifter on the way.

More to come.

Great! I have been WAITING for an update...

I too have the Gen V compressor.. But am told it will work by two different places that deal with Gen V wiring?

Watch this video.. from the beginning.
This is the way mine is wired up... And the pressure switch will bump the idle when engaged.
I used SwapTime for my harness, not the video guy.
I have not attacked the AC yet, but expect it to work? Compressor does have clutch btw..

Good luck!

I just caught up on your thread over at the mothership. WOW!! Great work and moving quite fast. Glad to see that you got the engine running so easily. I cannot wait to get mine running but I'm a long ways off. Need to get the paint done...the wait is killing me!!!

I bet the wait is killing you !

Hell, it's killing me ! I can't wait to see your project in color ! :P

Moving fast? Eh, doesn't feel like it sometimes! Remember, I am ONLY doing the powertrain this year . . .

As for the AC...
I am in search of an AC block that will fit the stock compressor... If I find one I will let you know.
Getting a stock line and having a shop modify is a serious option.
Will advise as I find a solution.

Get that shop moving ! LOL :fsj:

With Ed pointing the way again, we found one!!!

Thanks to Ed again, he pointed me to Cold Hose. Here's the link. I called them up and talked with a tech for a bit and said this should fit. I've ordered one and it's on the way. I'll let you know if it works.

Got a call from the shop to swing by...

Image

Image

Image

Image

Image

Image

It'll be in my garage Friday. Then my work starts. Plan is to get most of the work under the hood, inner fenders, rad support, and some wiring done before we get the doors, outer fenders and grill/light support back on to minimize paint touch ups. Once that works done it'll go back to shop for black window surround paint and final body assembly like hood, doors, fenders, tailgate, and a possibly a couple other ideas we've been throwing around.

Long time coming and very happy with results... :-bd

Got some work done. The engine wire harness is back in and engine put back together...to a point.

Image

Image

Image

Image

Got the a/c compressor adapter installed. Don't have a picture of the nut I used. It was a tight fit but it worked. Cleaned the surfaces and lubed up the seals.

Image

Image

Next up was the windshield wiper mechanism. I wanted to get that in before the a/c evaporator just in case any fitment issues. The gaskets were shot so I had to make some up. I used a sheet of neoprene rubber I had laying around.

Installed. But looking at how much they stick up I'm going to paint them black to match the rest of the bits.

Image

Image

The wiper motor needs a bit of cleanup and the rubber grommets replaced. I've got them on order so that will have to wait.

I finished up the remainder of wiring harness, engine bits, and brake lines.

Image

Image

Since I had the parts laying around, I installed the tailgate pins.

Image

Next up was more adapters from ICT for vacuum pump block off, oil cooler and trans cooler line adapters.

Image

For the vacuum pump removal, I used a couple grub screws to block off the oil passages but was not convinced they would hold up.

Image

Replaced with this kit.

Image

The two center holes are the oil passages and where the grub screws installed. It leave a lot of area exposed.

Image

The ICT plate installed.

Image

Next is the oil line adapter that uses AN fittings.

Image

Image

And the transmission adapter. Same setup.

Image

Next up is the fuel lines and wiring for the pump and sender.

Progress! Nice work.

So that AC block adaptor worked out, correct? I need to order one... Part number please?

Was the attaching nut an issue? Will it clear the fitting when attached?

EDIT: There was a link to this part.. I missed it.

No issue with the fittings. I'll grab a pic later.

Yesterday I began working on the front drive shaft rebuild. I've had it torn down but not cleaned. I'll blast it and rebuild this weekend.

I also wanted to see how the inner fenders and rad support fit so got those mounted.

Mounting the ECU and fuse box for the engine will be on drivers side. I'm going to lose a spot for the rad overflow or windshield washer bottle. I'll need to come up with something.

I ordered that part.. Thanks!

As for a rad overflow.. i am using a "HotRod" style one. Tall and skinny - fits on rad support. No pics...

Progress looks great! Be careful with that paint ! LOL Stressful I bet.

Been doing more investigation on the a/c and fan setup for the L83 swap. There's a connector for the a/c pressure switch that connects to a the high side of the stock a/c lines. The ECU uses pressure to determine the speed of the compressor.

Image

Since I don't and will not be using the stock lines and using a Vintage Air setup, another option had to be found. After a bit of research on the LT1 and other GenV swap forums, I found that you can get the pressure switch either as a weld in, crimp in, or bolt on options. Since I also need a drier, I opted for a drier that has the bolted on connector and the binary switch.

For CH4WHLN, here's the link:

https://www.bp-automotive.com/product/l ... ransducer/

Next thing on the list to resolve, engine wise, is an evap vacuum sensor. Since I don't have a evap system, I was wondering if I should just block off the vacuum line and connector open or if I could make or find a block off plate.

Image

I did a search and low and behold, my go to engine swap company ICT Billet happened to have a solution.

https://www.ictbillet.com/lsa-superchar ... gen-v.html

I've been working on the oil and trans cooler lines, and determining mounting locations for the ECU, ECU fuse box, my acc relay/fuse box, and a main relay/fuse box to replace the stock one. This new main box will bring the wiring into the 21st century. More to come on that.

I also did a test fit of the radiator and while I was at it, put the good bump stops and springs in. I got the radiator from an Australian company as I wanted a dual fan setup...it gets hot in TX and if one fan breaks, you have a backup. These fans are not staying however. They are cheap 80 watt fans that only have around 450 CFM per fan. I'll be swapping them out for PWM controlled SPAL fans.

Image

I have sourced an upper radiator hose that fits but still need to find a lower hose.
