Has anyone installed a 5.3 from a Silverado or suburban into a monte? I'm seriously considering it.

   Vincent,  I'm sure that you have probably seen the write-up on this swap by SS4ever and MCno1.

For a lot more information, Chevelles.com has a large library on this swap:

As does the LS1 forum:

Stay clear of donor cars that utilize the AFM (Active Fuel Management) system in 2007-2015 trucks.  They are plagued with chronic lifter collapse, high oil consumption, and stuck rings.

Well I decided to move forward with the engine swap.

I just bought a 5.3l motor out of a 2002 1500 Silverado, 110k miles it is complete with all the wiring and accessories.

Next on the list is a transmission, I have my eye on a 4L60E. what do you think of this tranny?

4L60E should work fine as long as you don't beat it to death or drag race. If you plan on abusing it, a 4L80E would be a better choice

Will a 4L80E work without tunnel modification? I was told that the tunnel had to be modified for the 80. I hope I have been wrongly informed.

You are right, it wont fit without some trans tunnel modification. 4L80E is definitely a huge trans. It would be some extra work to get it in there

I want to keep things simple, This project alone has plenty of modifications.  I don’t intend to race just cruse and open it up a time or two.

Now what year of 4L60E would work best?

I just finished a 4l80 install in my 72. Only mods I had to make was take the x pipe out of the exhaust, aftermarket crossmember and extend my column shift linkage about 2 inches. no tunnel mods needed. readjust pinion angle.


people who drive mustangs say I have a nice back bumper...

Larry,  I just completed the 4L80 swap as well.  No tunnel work is required.  ( I did give it a couple of bumps at the location of the speed sensor, just to add a little clearance for peace of mind.  The install goes much easier by replacing the cooler ports with banjo fittings. )

 

Jason,  I kept my cross-over by using a small pipe inserted between the collectors and the X.  It now crosses just aft of the tail-shaft.  The thing that concerned me was the wide body of this tranny.   The exhaust is only a breath away from the pan.  Because of this, I fabricated a heat shield that runs from the collector to the X-pipe.

 

Vincent,  if you really want to keep it simple, then use a 700R4 or 200-4R instead of the 4L60E.  Neither needs a stand-alone controller.       Doug

Well the tear down has started, I removed the old 350 and tranny and sold them as a set. The new/ used 5.3 will show up at the house this week.

Right now Ebay, Summit and Jegs are loving me, as I'm gathering all the parts needed for this project. 

If I can shake the cobwebs from my old brain I'll post some pics soon. As for the transmission I think I'll wait and look for a 4l60E

Way to jump right in Vince! There are so many options nowadays with drive lines, it would definitely be nice to go with an update!
I like the route your going
Every time I take a drive in my XL Denali I think what a blast it would be to put that setup in the Monte, it has the 400+ HP 6.2 with a 6spd auto. Moves that big beast down the road nicely
Green Tony!

Tony we though about a 6.0 for the 72, but we want the big block since its a true big block car. From what I've read the older style trans wont bolt on to a LS motor, not sure if that is true or not.

  For me alone this project is a big one; that’s why I’m thankful I have a few buddies that have done several of these conversions. They will be my go to men if I get in a bind.

 

Right now the plan for the 5.3 is to change the cam, springs and water pump hopefully making a little more HP. Later on down the road I will change the intake and injectors and maybe the belt assembly making it look more like a LS1, But for now the Truck look will suite me just fine.

 

Doug,

Connection wise  electrical & physical  is there any difference between the 4l60e and the 4l80e?  will the 4L80E connect to a 5.3?

  Yes, the 4L80E will bolt right up to the rear of the 5.3  and the ECM controller will operate it as well,  ...just use a 4L60 to 4L80 adapter harness.

 

   To support the other end, G-Force has a crossmember that's been fabricated for A-body 4L80 swaps.   I used it on my conversion, and it is truly a piece of automotive art.

 

http://www.crossmemb...vhs3mhibeng5m27

 

The slip-yoke is easily three times thicker on the 4L80, as it was designed to handle 440 lb ft of torque without complaint, vs the 4L60's 265 lb ft.  They make a U-joint that adapts the larger yoke to our smaller 1310 bearings on stock drive shafts.  It is the #448 adapter.   I chose to go the other way, and used 1330 U-joints on both ends of the new chromoly shaft that I built. (You'll need a different length drive shaft than your stock one.)  Either way that you go, be sure to use solid U-joints, not grease-able ones; they're twice as strong.

 

And likewise, you'll need a new torque converter to marry up the 5.3 flex-plate to the 4L80E.  I found that replacing the cooling line ports with banjo fittings allowed a much easier installation of the lines.

 

In a previous post, I discussed some costs of the conversion:  http://www.firstgenm...s-last-weekend/

Well my E-bay drop out, 5.3 came in this week, I was a little surprised how dirty it was. So I started to take off the accessories and clean it up. With a little paint she will look like new, but first I need to pull the harmonic balancer and change the cam and springs.

Looking good Vince...........I have that 5.3 Vortec in my Avalanche, several months ago I was getting KNOCK sensor errors so had to tear it down similar to the picture above. I replaced both knock sensors and harness and the cam sensor since it was easily accessible. The knock sensors are under the 2 round plugs in the valley pan in your photo. Good Luck!
