I will be tossing the fan and going with a dual electric fan setup. I wanted the LQ4 b/c I plan on mounting a power adder like a Supercharger or turbo. The only question I have right now is, what needs to be done to a 2wd 4L80E to mount to the transfer case in a 4wd, my Yukon is a 4wd. I plan on striping the engine down and rebuilding it completely. Any advice anyone wants to throw me, I'm all ears.

Here's a shot of my ride...

 

Nice. I could swear I see a spark plug broken off in the head. Hopefully it's just the porcelain snapped off.

 

I run an over haul shop for components to industrial gas turbines. We do crazy repairs all day long, stuff people, even our clients don't think is possible. I can most likely extract everything by welding a rod to the broken recessed ends and backing them out, even the spark plug shouldn't be a problem. If the holes are even damaged or threads I can weld the holes closed, re-drill and tap for a brand new threaded hole.

Nice buy!

To convert it from 2wd 80e to 4wd, you have to change the output shaft, which requires pulling all the guts out of the tranny and swapping the output shaft for 4wd unit. You will also need a 4l80e to t-case adapter.

Converting the truck from 4l60 to 4l80 is quite complex. Need both drive shafts replaces, chopped up cross member, some rewiring, cooler lines modified, reprogrammed PCM, ect. Look at KySilverado's thread...

Off topic but, By any chance do you have a picture of your truck with a front shot??? Just curious how that hood looks on a GMC... I have only ever seen it on a chevy and thought it might better suit a GMC Better... Thanks!

 

Might be worth it to sell the 2wd 80E and use the money to get a 4wd 80E? You got a great deal BTW

 

Still shopping around for a grill that I like that isn't made like sh*t, It will be a black billet grill if i can find one I like...Might just make one...

 

I was thinking about that, but I was going to gut it anyways...so I don't think it will matter that much. Anyone have an idea how much a new 4wd output shaft is? I want this trans as close to new as I can get it before it goes in. I will also be installing a shift kit before she's ready to go.

 

damn nice deal! and may i suggest a transgo hd2 shift kit. I love mine

 

does that motor have cast heads thats what the pic looks like if so i thought only 2000 models came with cast heads
