COMPLETE 1999 LS1
$2500 This is a COMPLETE 1999 LS1 that came from a running/driving car I purchased. I'd originally intended to use this engine for my LS swap, but ended up using a different one so this sat in storage awaiting my next project......which simply hasn't happened. So off to a good home she goes!
Located in the Chicago area.
Here is the car as I'd purchased it:


The engine is very complete, right down to the exhaust bolts. The starter is missing in the pics because I stole it for my LS build, but I've already ordered a replacement.

Re: Complete LS1 and built T56
Both. This is from before the trans sold. It's no longer available, just the engine.

Re: Complete LS1 and built T56
I really have no idea and I sold the car as a roller. 130K comes to mind, but I couldn't be sure.

Re: Complete LS1 and built T56
Also, the engine comes with:
- Complete wiring harness
- PCM
- 1 3/4" stainless headers
- The stand that it's on.
I'll try to grab some pics of that stuff soon.

$6K for both. Located in the Chicago area.
The trans is a T56 I'd purchased off of these boards, and rebuilt over a few winter weeks to keep myself busy. Like the engine I'd intended to use it for my next project which hasn't happened yet.
Here is the car as I'd purchased it:


The engine is very complete, right down to the exhaust bolts. The starter is missing in the pics because I stole it for my LS build, but I've already ordered a replacement.






The Trans:
- Steel 3-4 shift fork
- Bronze fork pads
- All new bearings
- 1st & 2nd CenterKevlar Friction Rings
- 3rd, 4th, 5th and 6th carbon kevlar synchronizer rings
- Brass reverse synchronizer ring
- Front and rear seals
- Billet keys
- Retaining springs
- Shifter bushing
- .002" preload on the main and countershaft
- .002" endplay on the countershaft extension

Re: Complete LS1 and built T56
I'd prefer to sell them both together considering how great they'd be for a swap/build. But I'd sell the trans alone for 3500.
