:roll2: at the trail and error part of engine building. It is more experience and know how. I really don’t see anything wrong with paying a professional for his skill, expertise and specialized tools to make sure you don’t A.) blow your shit up B.) cost yourself more money then it cost to have a professional do it in the first place. Lets face it internal high performance engine parts are NOT CHEAP, and LS1 block are around $1000 new. A few simple mistakes can cost thousands. So if you don’t know what you are doing you can either A.) trust the “internet professional” or B.) pay a real pro
