1998 Tahoe 2DR 5.3 swap

http://i1093.photobucket.com/albums/...psb0720860.jpg

Well the vortec gave up at about 228k miles..coolant in the crankcase. It served it's purpose but drank gas more than usual, kind of gutless with 33's on it and a pain to to work on. So 6.0 swap is in the mix now!

still have to locate that perfect complete engine, I expect to pay about $600 for a decent 5.3 with everything on it. Then I will decide on headers or not.

I won't be doing teardown for about a week but will try to keep you all updated. Wish me luck.

Any more pics of the tahoe? How much lift? I've got a 94 two door blazer that I'm finishing up an lq4 in. I want mine to have that stance.

has a 3 inch body lift, 2 inch lift blocks in rear and cranked up torsion bars 2 inches in the front. About as high as I can go without redoing the front suspension. Not big on the body lift though, pretty sure it's the reason it rides rough and the bumps on the road are multiplied. More pics when I get home this weekend.

Thanks

I've got a 2-door '98 Tahoe 4x4 myself that I plan on swapping an LS1 into. The stock 5.7 Vortec has just over 250K miles on it and runs great but I want some more power.
Here's a shitty pic. of my rig:

I'll be keeping an eye on this thread.

Looks good! After having LS motors, I love em.

update:
Project went from 5.3 to a 2001 6.0 I found for $500. everything there but no intake assemebly, wiring or PCM.

found a deal on ebay where a guy sells 0411 PCMs and programs them with the basics for $125 shipped no core.

got a cold air setup for $60 from ebay for a 01 silverado..looks good.

got a new delphi 01 MAF to complete the take. $77 shipped.

got a flowmaster 40 series 3 inch in/3 inch out for $60 shipped.

looking at a 01 stock 5.3 wiring harness for $150 shipped or a stand alone for $490. For $300 I think I can thin out the factory wiring harness and customize it to my liking. Looking more into the harness now.

also looking at LLP headers and off road ypipe since they are about $499 shipped and stainless steel.

Also have a 46l0e/stock convertor from an 05 silverado to bolt up. Just got to figure out how to mate it to my NP8 transfer case...anyone know? This should eliminate any need for a new flywheel and spacer. Plus my existing transfer case is leaky and needs to be split to reseal.

oh yeah and got a SPAL fan controller and extra relay kit for it to mount the dual fans. I may actually mount this before I start on the swap. I found crud blocking the spark for #7 cylinder to fire. Put a new sparkplug in it for now and it does ok, but I know Im on borrowed time. Im at 231k miles now.

From alot of reading from the forum, this is what Im thinking it's going to take to make fuel lines. No progress on fans yet, going to pick up the new transplant today hopefully from salvage yard. After dickin with craiglist sellers and beong done with them I found the entire 2001 6.0 from a GMC denali with 113k miles, all accessories, wiring, PCM, MAF, DBW pedal etc for $1200 locally. Going to try and tackle my own harness. No one can tell me yet if my NP8 transfer case will bolt straight up to my 2005 4L60E

Pics as I get the motor.

If the transmission you are trying to use came out of a two wheel drive truck then no, it won't bolt up. The 4L60E in a 4x4 has a shorter output shaft. Why don't you just use the original 4L60E out of your Tahoe?

The tranny is from a 05 5.3 4x4 truck. Want to keep it more plug n play if you know what I mean. Plus I never seem to have a problem finding later model 4L60Es and don't have to change anything for it to mate up to the new LS motor if that makes sense.

In that case it should bolt right up to the original transfer case out of your Tahoe.

Well good to hear, Im thinking it should fit but tryting to get as much ordered and together before I pull the engine.

So picked up the 113k mile 6.0..gave it a little bath before undressing her a little.

got my dirty dingo mounts in the mail today. Going to take off all the not so necessary stuff for the engine and start figuring out some wiring. Didn't realy want drive by wire but got to go back and pull the pedal assembly from the truck and other little tidbit stuff.

currently driving with...

Nice looking 6.0. Can't wait to see pics of the swap progress.

Mickey, I had alot of questions for my swap so I wanted to be as informative as I could for the next guy..kind of a pass it on type deal. All the info is here but got to jump through several threads to find everything. Hoping to make it pretty cut and dry for a 1998 swap person.

I hear ya. If you have any questions, just ask. I did something similar and had lots of questions myself.

Oh Ill have questions for sure..lol

Fuel line stuff came. Got to wait til I drop in the engine before I cut them to length.

in re gurads to the lpp headers: i have them on my truck and i love them i live in WI where winters are very harsh and salt eats everything alive and these headers have stood up to the test as to where my buddies silvy with pacesetter armor coating are already starting to rust after one winter.

More goodies...
EBAY cold air intake ($60), fitted with MAF supplied with motor purchase. 0411 PCM programmed EBAY ($125 shipped no core) plug wires ($48 shipped) NGK TR55's ($20 shipped)
Measured OHMs one new wires 230 OHMs, works for me.
http://i1093.photobucket.com/albums/...ps87cccfab.jpg

Drive by wire pedal, wiring harness, and TAC module, caame with motor purchase. Thank goodness the salvage yard let me get the wiring, spent a good hour fishing it out of the stock dash harness but worth having complete.
http://i1093.photobucket.com/albums/...pse2d37ff8.jpg

got in a bunch of little bolts, gaskets etc.

Just ordered some 07-11 LPP stainless headers..experiment to see if they fit, they were only $450 shipped and two new bosch O2 sensors $35 shipped each. Then some stock motor mounts and stock trans mount $30 shipped from RockAuto.com . Then a Lextech AC bracket kit. $250 shipped.

Then noticing my stock NP8 transfer case is leaking like crazy now on a long trip...sigh..lol

The body lift has nothing to do with it riding rough, the fact that you cranked up the torsion bars is why it rides rough.

i just finished this build about a year ago. definately worth it! check out my thread its pretty detailed lol

http://www.ls1truck.com/forums/lsx-t...ders-pics.html

Yes I browsed that thread long and hard, took a while..quite a novel.highs and lows.

Got the Lextech AC bracket kit ($250 shipped)..the bracket looks really good, the finish is awesome. Still have to clean up the engine, shine up the aluminum brackets, clean oil pan, install new front rear seals, paint the block and get it ready. Still waiting on the NNBS headers to get here, NP8 transfer case, 02 sensors.

http://i1093.photobucket.com/albums/...psb80c29df.jpg

Got the headers in..look good they are the NNBS ones no EGR stuff which is cool but hope everything clears. For the money they are thin walled but look good otherwise.

Mated up my 40 series muffler to get a visual

lmfao!!!!!!! :lol:

I have a 94 Blazer and have thrown the idea of this swap around for a while. Could you not find a motor with a throttle cable throttle body?

Any update on this build?
