I thought that there would be a 5.3/4.8 stamped on the block as well?? At least that's the way mine is.

Ok...this just in. I can not seem to determine if the pistons flat or dished. If I had to guess I would say flat. I did find 5.3L cast in to the rear of the block and also discovered the block was aluminum. With this information I do believe I have a Gen IV LH6. I cant seem to find the stock horsepower number. I only want this to use as a baseline before adding a few go fast parts. From what I am finding out it appears there is a wide range of interchagability between the LS family engines. Thanks for everyone input. If you can add to my finding feel free.
