Yeah, another LS swap

[reddingcruiser]

What do you usually use for a fuel tank on your other builds?

Depends. Typically I use a modified GM in - tank pump in a stock FJ40 gas tank. The gas tank mods require some invasive surgery so I use new steel tanks since have no intention of leaving this earth before I have to. I've worked on used tanks but it's not worth the risk.
This picture is an early prototype from years ago, but you'll get the general idea. There are aftermarket pumps that do the same thing. Either way, the trick is getting the pump between the tank baffles, in the deepest part of the tank and between the seat rails.

Can you tell me how you did your transfer case shifter?

 

[reddingcruiser]

AA twin sticks. I'm a big fan of them. You can get as fancy as you want.

Well, we wrapped up this build last Monday, dealt with minor issues on Tuesday and left for the Rubicon on Wednesday (no pressure ). We were under a deadline to make our departure date so not a lot of final build pics were taken during the week leading up to our trip. However, the 40 performed great! No significant issues, just a little bit of a learning curve by the owner getting used to the LS throttle response and extra horsepower. Next on the list of improvements for this one is an Orion t-case.

What really matters is we that had a fantastic trip with just the right number of folks at Rubicon Springs. I'm proud to say I've had my fingers on three of the rigs in the first picture below. For the two 40's in the middle, this was the first Rubicon trip for the rigs and their drivers.

For those unfamiliar with California during fire season (we used to call it summer), the smoke you see in the picture below is from wildfires burning across northern California. Most of this smoke is from fires burning in the central valley, northern Bay area and coastal range, making it's way east to the Sierra's and up to 7,000 feet (and more). This is normally one of the most majestic views from the Rubicon Trail.

Just flipped through this thread as I am going through a similar swap on my 40 right now, nice and clean install. Could you share the details on your upper rad hose setup?

The hose sections are cut from a stock 2002 Chevy Silverado upper radiator hose. The aluminum section is a air bleed adapter/steam line connector from Jags That Run (may be a new name now) with a second of aluminum tube welded to the downstream.

Great write up! Curious which radiator you use (19x26)? I need to stuff a bigger one in there. Will need to modify headlight buckets I guess on my '69. Thanks!

The new LS sitting in it's new home.

Can you share some info and pics on your LS mounts? Also, are there some specific dimensions that you have found to be ideal for placing the frame mounts? I will be running a mechanical fan setup as well but am a bit confused about the best way to determine actual mount placement on the frame. I would like to be as far forward as possible to allow for the longest rear drive shaft I can go with. It will already be short with the TH400/NP205 connected to an early 40 centered rear output axle assembly.

Plugging away on the radiator and air intake today, while waiting for a bunch of braided steel hose and fittings to come in for the A/T cooler and fuel system.

I've used Lokar, B&M and other aftermarket throttle cable setups but still prefer the OEM GM cable and bracket. The length is perfect for the FJ40 and requires only a small mod to the top of the skinny pedal and a round 5/8" hole through the firewall. The Holley aftermarket throttle body uses a spacer that moves the throttle lever and air intake forward 1/2" so some minor mods to the OEM bracket are required.

This motor originally came with factory throttle-by-wire (TBW) throttle body, and while I'm not opposed to TBW, I prefer converting back to a manual throttle body when I can and reprogramming the PCM. The TBW box can be a bit of a challenge to fit cleanly against the firewall, depending on the look you want. This is just easier and looks stock from the cab.

Don't panic, the throttle cable is just sitting on the booster! It fits neatly into the firewall just slightly above the original Toyota throttle location. The new cable needs to come in a little higher to allow enough travel for full throttle. Not sure though that you need full throttle from an LS 6.0 in an FJ40.

Planning where to cut the air intake and add bracket.

More layout work in progress.

Nice job. I am in the process of this right now. Do you remember the GM throttle body cable you used? I found one for a 2002 Silverado AC Delco part #

15040848, is that the one you used?​

Thank you.

Can you share which in tank fuel pump you recommend now?

Thank you.

Just incase you don’t get a reply I installed a submerged LS Swap fuel pump from Speedway Engineering and the fuel level indicator from Dakota Digital. I ran a single line up to the engine, Speedway also sells a filter / regulator that has a return line that circulates back to the tank.
@reddingcruiser was a huge help when I LS swapped my ‘67.
