1998 Tahoe 2DR 5.3 swap

[smkur50]

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.

[smkur50]

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.

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?
