1998 tahoe LS swap

[orange57]

any more update?

I've been doing some research on this as well, and debating what I may want to do. I've been looking at the 5.3 as opposed to an LSX. The 5.3 shares a lot of the same characteristics, but is Iron instead of Aluminum. Also read that some run the 5.3 heads on their LS1's for better flow.

Just a thought

Im thinking im going to go with a 5.3 unless I can score a decent ls1 for a good price...

Got the motor pulled.. but nothing else done yet.. waiting on my bonus so I can get me some parts...

I was taking a look on car-part.com, you can get a 5.3 for 4-500. however i'm not sure what all comes with those.

Thanks for posting this. I'm looking forward to watching your build progress because I'm planning on a similar swap down the road a bit. The 10 bolt rear end is coming out of my '92 Blazer this weekend to be replaced by a 14 bolt semi floater. After that I won't have to worry about going too big! Ideally I'd like to go with a 6.2 and a 6L80e, but it all depends on what's available when I'm ready. Anyways, I'd really appreciate you posting any issues you come across and how you solve them.

i think I also saw him on ls1truck . com also, with a little more detail on his build/swap.

been a little bit... didnt get anything done until last week.. TAX RETURN!!!

Anyhoo... picked up a 2002 5.3L with 120k.

Dirty Dingo adjustable motor mounts

and a spacer for my flexplate.. This gets a little confusing.. but basically if your 5.3 comes with the dished flexplate and you are using your old model 4l60e 96-99 i think, then you have a torque converter that has a shorter center hub on it... in order to use it you have to use GM spacer 12563532 and use the longer bolts 19257940. You have to install the spacer after the flexplate so that it cradles the TC. There is a great writeup here... http://www.pirate4x4.com/forum/11065304-post1.html
You will also need to elongate the holes where the flexplate bolts to your TC... the bolt pattern for the TC is about 1/2" smaller than the FLexplate.

Painted my valve covers

Also built a bracket to mount my LS ECM on the passenger fender well.

got my flexplate bolt holes elongated...

Got some fuel line parts in...

Also got my engine in the bay today..... almost.... the motor mounts are in but for some reason it doesnt want to slide back enought to allow me to easily mount my bellhousing.. the pass side slides back but the drivers side seems bound somehow... Nothing is obstructing it but it wont move... I am about an inch off...

Great build looks great . What parts do you have for sale ? Looking for a nice condition cold air kit .

 

[2drhoeon4s]

I had a k&n intake kit but I sold it

 

[2drhoeon4s]

motor is in!!!!!!! Turns out there was a ground bolt in the way keeping me from sliding it back to the trans.... anyhoo... got my intake today and I threw it on there to see how it fits.. Its coming together...

 

[SwampHound]

Looks great man! Any plans for performance parts? Headers, tune etc?

headers are on their way... i plan on getting it tuned later on.. i want to drive it for a while and get any kinks out before i try anything power wise...
All custom exhaust with cutouts also...

 

[Monstar_est87]

Damn this thing is coming 2gether real nice like... that wiring looks a nightmare...

 

[2drhoeon4s]

that is all the old harness... im keeping parts of it.. it just have it all pushed over there... and Im stalling on dealing with it haha..

 

[Chevrolado]

Sweet! Definitely following the progress on this one.. Nice work so far.

 

[2drhoeon4s]

got my old exhaust out..... man the shop i paid to weld the cutouts on really did a great job haha... I cant believe that the little 2 1/4" downpipes sounded so good on my old engine..

Video of her before pulling the motor cutouts closed.

Also got my fuel adapter lines made up..

 

[2drhoeon4s]

got a few more things done today...

Got my cutoff flanges off of my old exhaust..

Mounted my Radiator and flexalite dual fan setup.

also mounted my overflow tank.

I am doing away with my EVAP system and i have this hose... it is on the drivers side.. looks like it goes back to the gas tank? How do you guys remove this?

Also got my grille put back on... to me this helps me feel like the project is moving along faster haha...

Check out my Custom BABY sticker I had made a while back..

 

[2drhoeon4s]

Got my old harness out of the truck.. I am going to be repinning it instead of running 2 ECUs and buying a harness.

Man it sure is nice having photo/video equipment at my house.. Extra lighting rigs came in handy.

After about 5 minutes...

2 hours later and I have cut and labeled all of my new pins for the 411 ECM. Still have to get connectors and wire in the Coils and injector plugs.

 

[Gzes]

Coming along nicely. Where did you get those cutouts if you don't mind me asking
