I am swapping my 5.3 for the 6.0 within the next 2 weeks.
I'll have a spare 5.3 with 50,000 miles and in great running condition with never a problem (ever) & has had Mobil 1 Synthetic since I first got it. (I am a loser and keep all the receipts to prove it)
I can provide VIN of my truck, etc. if needed.
Plus, you can feel free to come by and check it out and see how it runs before the swap in a couple weeks if you're in Houston area!

It will be a complete takeout minus steering pump, starter, water pump, etc. (the stuff on the front...lol)
It will, however, include the fan, the complete intake, etc.

How much is it worth?

 

I bet you could get someone on ebay to give you around 4-500...dunno...

 

I tried to sell mine for a long time. I started asking like $1300 (only had 19,xxx on it) then I came down eventually to $500 and I never got ANY response. I ended up just using it in my work truck! I wish you more luck than I had!

 

I agree, don't expect anything above $600 for it.

 

That'll pay for my headers (almost).

Thanks.

 

what if u sold in parts in stuff

 

Im new to ls1 tech so I'll start by saying hello. Im intrested in you engine. I have a 2000 Silverado with the 4.3l V6 and have been wanting to swap it out since day one(long story). If you are still intrested in selling let me know I'm in the dallas area.

 

You will get more parting it out! Trust me!

 

Interesting info, I will be in the same situation soon. Building a 5.3 to stroker 382 right now. Have the 4.8L motor stock IN ADDITION a crank, rods, and bearings to convert to a 5.3L.
