Tearing Down an 8.1L BIG BLOCK CHEVY V8 That I Pulled From The Scrap Bin. Why was this thrown away?

For parts visit www.Importapart.com or www.Pro-Rebuild.com Today we have the BIGGEST of big block chevrolet engines, the 496ci Vortec 8100. I found this engine at the BOTTOM of a scrap bin and dug it out so I could bring it home and tear it down. Why was it in the scrap bin, how did it get there and more importantly, what was this out of? These are all things we aim to find out in the video as I tear this video down to a bare block to find all of its issues. The 8.1L L18 Engine debuted in 2001 for the GMT800 platform of GM trucks, offered in 3/4 and 1 ton Silverado, Sierra. Avalanche and suburban/Yukon XL 2500. These engines were also installed in medium duty trucks and step vans as well as generators! These engines are built from the same architecture as their predecessor, the 454 or vortec 7400. Producing 340hp and 455lb ft of torque in factory form, you can imagine how well they tow!

My name is Eric and I own and run Importapart, a full service auto recycling business. Part of our model includes buying and dismantling core, bad, and broken engines to salvage the good parts and recycle the rest. We do not rebuild engines, merely supply parts to those who do. As always I hope you enjoyed this teardown. I love all of the comments, feedback and even the criticism.
