      So I'm building what is basically an iron block ls2 to go into my 03 Tahoe (LQ9 short block, 799 heads). Wondering what would be a good...

      LS2 is a 6.0L with 243-799 heads yielding 10.9:1 static compression. TrailBlazers SS weighed over 4000lb. That he will REQUIRE a smart...

      4.10s will help immensely, but 799s are still going to give you compression in the neighborhood of 10.9:1..... We are talking 93 octane...

      I'm gonna be running my tahoes stock flex fuel injectors(l59). Would those work? Are ls6 valvesprings acceptable for 6500-7k rpm?
