I am currently in the planning phase of a LS motor build. I am planning on building an LS3 but i see that the LS9 block is about $32 cheaper on summit. It really is a insignificant differance but it got me thinkg. What would the advantages be to use the LS9 block instead of the LS3? Not going to do any forced induction with this build. what is everyone's thoughts?
