I'd love one too, this is my backup to the 1FZ plan.

I got 35s and 4.10s with the old 5.7L vortec. It works great, I feel no need to do anything to it. Since I only have 255hp I would imagine the LS with the stock gears and 37's would be somewhat similar. Might be holding 3rd more often but I don't see an issue with that. If and when I go 37s, I will try it before doing any gears. I am also going to upgrade to a 5.3L.

Also, I think the tune makes a huge difference. I got 3 Chevy work trucks, my Cruiser is tuned and drives like none of the work trucks.

Cheers

Thanks for the kind words.

We had not come across those before. It looks like they are designed around using the stock transmission. One of my first thoughts is that they would make the exhaust trickier, but I've never seen them in person, let alone in a truck, so who knows. Hopefully someone that's used them before will chime in.

I exchanged an email with them on these mounts. If you notice in the description, it says they shift the motor slightly to the left to clear AC. Which works with RH drives, but they did not think it would clear the steering box on a LH drive.

Easy fix... Get a rhd cruiser

@Brentok Thanks for the info.

Marks LS mounts are also designed to be used in conjunction with the accessory brackets they sell. That was the word I heard the last time I inquired on the mounts.

I have marks engine mounts. Accessory bracket and 4l80e to our tcase adapter. Will be installing within the next month. I will start a thread

The cruise control works exactly like factory. That was one of the less difficult parts of the swap. Having a throttle cable setup did make it easier.

Clean build! Can you please go into a little more detail on making it work? I'm throwing in a 5.3 dbc right now. Thanks

 

[LXCRAWLER]

Thanks for sharing because of this thread I am also doing a swap. I am curious what shifter cable did you use.

The “what” is an FZJ80 with an LQ9 & 4L65E. The “why” is that we’ve got a customer that does lots of traveling and towing with his supercharged 80. Hammering on a 1FZ with a blower that is hauling an 80 full of gear, followed by a trailer that is even more full of gear, up a Rocky Mountain pass was turning into a frequent occurrence. The customer was looking for a drivetrain that could tow with less stress and run regular old 87 octane. The 390hp version of the LQ9 was a good fit.

First, you start with an adapter from Advance Adapters:

Then, you add a transmission with an output shaft that is way too long:

Next comes the not-so-cheap thrill of taking this:

...and making this:

On goes the adapter:

...a couple of shots of the assembled drivetrain:

The engine covers that say “Corvette” & “5.7L” will have to go, since this is a 6.0L going into a Land Cruiser. We’ve got some fancy plans for those.

The factory shift pattern is different than it will be with the 4L65E. Again, we have more fancy plans for that later.


Test fitting the drivetrain:

If you screw up, it's an expensive mistake.

So did you cut the output shaft too short?

Man that is impressive. Now you've got me rethinking my 1fz-fe rebuild.

Original ECM connector E7 Pin #10 Black wire. you'll need a signal conversion module to connect between the new engine and this wire. The module we used is the older version of this one - Tach Module
