Thats the article I read and then did a bunch of research on dwell time. The 4.8 has the most dwell time of any ls due the 3.27" stroke which means FI works better than any LS. I got mine for 500 from oil pan to manifold out of a truck with 120k. My goal is 780rwhp at 10-14 psi and 2700 lbs and the ability to make 1k if i need to.
