Registry 8x Series V8 Swaps (6 Viewers)

[NeverFinis]

I don't know a R2.9, but I think the R2.8 is too small for an 80. I am considering it for my 1985 4runner though. A 5.0 V8 Cummins would be much better, but it was a problematic engine, with limited availability.

IMHO, a L96 + 6L80/90e is as good as it gets. Iron block with power and torque, coupled to a heavy duty 6 speed transmission.

 

[Delta VS]

Would you recommend the newer 4cyl R2.9? That Proffitt did into an 80?

We put one in an 80 for a customer. They drove it for a week and pretty much tossed it back through the window at us.

Discount tire in the 80’s style ???

Love my L96 and 6L80 trans, pulls our camper uphill as well as my 2022 F150 3.5

Evening Troops,
Below is a picture of the bracket for the hi/lo shifter I had with my marks adapter for my ls swap, and below that is a picture of the hi/lo shifter and as you can see there is no way its bolting up!
Anyone else have this problem? Obviously I will have to fab up or modify the bracket included, I was just wondering if the original bracket holes line up where the shifter mounts in the cab, so it would be a case of just cut the bracket and and add new material with holes to suit my hi/lo shifter!
Thanks all!

The Mark's 4WD adapter plate is designed for the earlier 4WD shifter.

So I'll have to fab one up then, thanks for the reply!!

I ran into the same problematic issue as you. I had to be creative and fabricated an aluminum plate to make it work.
Easier to cut AL than steel plates with a power saw. Wish I had access to a water jet cutter.

Thanks for posting the pic!!! Much appreciated

Here is an example of the cut and weld method using an earlier shifter.

 

[NeverFinis]

16.3 mpg L96 + 6l90e + 4.10 gears + 35" tires.

 

[NeverFinis]

Doing odd and ends, and tried to install a @Delta VS crossmember front skid... IMHO, too little clearance to the stock 6L90e pan from a 2020 GMC Savanna. Maybe 1/8"? I am not sure how much is necessary but I think more than 1/8".

The skid was designed for a A343F/A442F and not for a 6L90e transmission...

I mean, I did a good job of leveling the L96 side to side, despite moving the engine mounts a ton...so there is that..

I could look for a different transmission pan or I could modify the Delta VS skid plate, but there is no way I will be able to bend it as it is. It is one thick piece of steel... Cut a seam, bend, weld the seam back together.

Anyone else run the Delta VS front skid plate with a 6L90e?

Apparently there are no low profile 6L90e pans due to the TCM, and the filter positioning.

Time to butcher Delta VS front skid... The plan is to cut a few inches out, turning that cut section upside down, and welding it back in.

Well now I have to drive mine to work and see what my scangage says. Only difference mine is on 33’s

Why do you need more clearance? The transmission should not be moving up and down much at all (maybe a tiny bit of torq rotation transmitted from the engine?) and the plate sure will not move under normal driving. Even if it was to flex up a bit (not likely) from a big hit, it would be a smooth flat surface pressing on the pan a little as opposed to a pointy rock. I'd bolt it up and drive a bit. Maybe later check for witness marks? In your wheeling style are you sitting on the belly pan with wheels in the air a lot? Maybe if you plan to hit it a lot this is a concern? Sounds like a lot of cutting and welding for a "maybe". @Delta VS could probably tell you the amount of force it would take to deflect that pan 1/8.

Just getting started on my swap, an LS3 and 6L80E, and had a question about what to keep from the Land Cruiser. I pulled the engine, transmission and transfer case complete with all wiring attached. I have the full engine harness removed from the Toyota ECM behind the glove box and removed from the engine. I also have the full harness that came out with the transmission and transfer case. Seems like I don't need to keep anything else off the engine or transmission besides the oil pressure and temp sensors. I'm looking to get the Toyota engine and transmission out of my garage and want to make sure I'm not getting rid of anything else I might need. Thanks

I'd throw some washers between the frame and skid and fry bigger fish ...
Circle back later when ya need that clearance

It is the rotation of the engine due to torque, not really the up/down of the engine (or something impacting the skid), that I am concerned with.

Those poor 1FZ-FE motor mounts.

stand back, I decided to do some math...

It only takes about 1.5° degrees of engine rotation to close that 1/8" gap at the edge of the 9" wide transmission pan (4.5" from center of rotation).

This equates to about .28" upward movement at a motor mount, assuming the mounts are 11" from center of rotation.

I am using estimates as I am not in the garage today...just trying to see this is indeed an issue to be concerned with and should I get actual measurements..

One broken engine mount surely equals one busted transmission pan but under normal circumstances, I don't think it is realistic for a motor to move that much on its mount.

This makes me less concerned... I think your idea of mount the skid as is..look for witness marks is what I will go with...Thanks

From the top of my mind, you will also need everything that goes to the t-case. Maybe save the A/C clutch line as well. It is bundled with the oil pressure line.

I like your idea but not all the bolts are on the same plane. It doesn't mount flat.

 

[wiynwiyn]

There are pics earlier in this thread, but they might be hard to find.

I made a little bracket to move the mount point further away. I also used flat head #8-32 1/2 screws underneath to attach it to the transmission shift plate. Drilled into the plate with a bigger drill bit to recess the screw heads to allow them to sit flush.

Thanks for sharing this great picture. I'm getting the dakota gss-3000. I'm planning to use the LC bulbs, stock look.

I would keep all the harnesses and then get rid of them after the swap. Better to have them and not need them...
