Everyone is at different levels of knowledge and experience when it comes to engines. We have LS engine upgrade guides for those looking for stepping stones to engine upgrades. These are on our On All Cylinders Blog. They’re basically road maps that go from mild to wild. You can view them in the guide to LS engine specs and upgrades article. It's broke down by displacement, RPO code, 24x or 58x, VIN code, and block material. Use the keyword search in the blog to search for a specific RPO code. An example is “LM7 engine upgrade”.

We hope the community finds this info as helpful as we do. Sharing info and knowledge can be a benefit to just about anyone. If there's other info you think we should have as a resource feel free to share. Your idea could end up as a new article to help out the community.
