Today we have the BIGGEST of huge 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 arrive and much more importantly, what was this out of? These are all points we aim to figure out in the video as I tear this video to a bare block to discover all of its concerns.
The 8.1 L L18 Engine debuted in 2001 for the GMT800 platform of GM trucks, used in 3/4 and 1 heap Silverado, Sierra. These engines were also installed in medium task vehicles and tip vans as well as generators!

Component of our design consists of acquiring and taking apart core, negative, and damaged engines to salvage the good components and recycle the rest. We do not restore engines, merely supply components to those that do.
