Default Newbie swap question

I recently changed direction on the restoration of my 69 camaro and have decided to go the LS swap route. I bought a running 2003 GMC Sierra 1500 (220,000 km) with a 5.3 in it. I’m going to be removing the engine soon and my newbie question is are there any other parts (other than the obvious; ecu, harness) I should be saving for the swap? I don’t want to discard or overlook something.

Really appreciate any advise.

Cheers,

Frank

Thanks! I plan to part the truck out and get rid of it. Just hate to miss something and leave it on there. Anything with the fuel system I should be grabbing?

What Jimbo says...but, even if it's a 4X4, save the trans. I've converted several 4X trans to 2X for my swaps.

Why would you want to save a 4L60? It’s barely worth its weight in scrap. It can’t even handle full throttle shifts, the PCM actually has an “abuse mode” function that cuts power during shifts to prevent it from blowing up. Total garbage. Never should have been installed in a truck and has no business in a modified car.



Leave it with the truck when you scrap it.

Awesome! I appreciate the input. The truck is a 4x4. I’m planning to get a T56 the LS....but that’s a ways off still.

You won't regret the T-56. I run a T-56/5.3L combo in the A-body wagon in my avatar. I ran a 4l60e before. Pretty boring...
