Hi guys. I bought a tuning book on the LS1 and LS6 motors when I was in at Kartek in 2007. Is there any reason that the LS2 is any better or worse than the LS1/6s, or why it would have been excluded from the book? We're possibly looking at moving to Oz, and the LS2 comes in on the engine size limit over there, so that's why I'm looking at transplanting into my race truck in place of the current Pontiac 406ci that's in there. Check out http://www.windust-ops.co.uk/venom.html to check the truck out. I understand the LS2 is popular out there - just looking into whether our truck would meet the regs. We currently live in the UK.
