Default Starting my LS3 Swap - EDIT: Swap Done.

Ill be posting pics as the build moves forward but for right now, I ordered all the parts for the swap including the 376/480 LS3 Crate engine.

Also went with a Dewitts aluminum radiator with oil cooler and oil cooler lines kit.

On the back end, Ill may have my LS6 to sell (minus the parts needed for the LS3 swap)

The LS6 needs the bottom end gone through to replace the main bearings but still runs strong and was dynoed at 351 RWHP in 2014. At this time I'm not sure if I will sell (if at all) the LS6 as is or after repair.

As time moves on, Ill post pics - Car goes into the shop on Tuesday (10/11/2016) to start the swap.

I love my LS3.

Question, why didn't you go with the 500hp version? I think it has a slightly more aggressive cam, not sure of the spec's.

Anyway, good luck with the swap.

Thanks!

I havent decided what to do with it yet.

It has an issue with low oil pressure when warm. The census is the main bearings are going out.

It is a Thompson Motorsports LS1/LS6 replacement short block with forged internals rated to 700 hp. Tuned at 351 RWP

I may just fix it then sit on for a future project of if someone made me an offer I couldn't refuse ....

The motor should be out Sunday.

How old is the Thompson Motor? Give us a call when you have a sec, We can likely help you even if it is for another project in the future.
Thank you,

I look forward to following this. I am in the market for a roller C5Z or C5 FRC so I can start it right away as a project. Just not easy to find one.

Looks like the clutch needs attention - rather than replace the disks, Im just going to replace the entire clutch assembly.

Anyone have a lead on the best place to get a clutch for my swap?

I need it by Friday at the latest.

TIA

Drew

I had real good luck with an OEM LS7 clutch in my old car (6.0 LS swapped BMW). I got it overnight from Summit Racing for a good price (pressure plate, clutch disk, and flywheel). I live in Buffalo and got it overnight at regular shipping price from Cleveland.

I see you're in Gilbert AZ - I think Summit has a location in Reno, NV. Might be worth a shot.

Had a week delay but things are moving forward again.

I decided to replace the Mantic Er2 Clutch (with only 32k miles) for a brand new Mantic Er2. Took 5 days to get here.

Now, the only thing I'm missing, which I just found out today, is the MAP extension harness.

She's getting closer.

Great build!

How hard was it to line up the new engine with the torque tube input shaft?
