Scoff??? I think that's ridiculous. This engine has iron cyl. liners. I have an LS1 that I ran for 125K sitting in my garage right now. If I had a '04 or older vehicle I'd love to drop it right in in place of a 4.8, 5.3, or whatever engine. About the trickiest thing about the LS1 is that so much oil splashes around in the engine the PCV system sucks it up and deposits it in the intake tract. A lot of people set up a catch can arrangement. My LS6 has an improved PCV baffle system in the valley area of the engine that corrected that fault. I like the LS1 over the 5.3 engine any day. The confusing issue nowadays is the different iterations of LS engines that aren't always compatible with each other like the Gen III, Gen IV, and Gen V versions. You have to pay attention to which ECM you're going to use along with reluctor wheel of the specific engine you have.
