In the world of drag racing, LS engines have been making a big splash sense they first showed up in the burnout boxes in 1997. They offer a great platform to build engines whether you are running 8s, or 12s.

Most of these have to be done for those running higher end classes, but we wanted to make sure we covered it all.
