I've always like the LS. If your looking to play with it later....when discussing a Ford V8 turbo project with a turbo shop last month they couldn't stop talking about the LS V6 engine..they are getting serious power out of it with minimal boost, he literally wouldn't stop talking about it. His story was that the V6 started out a porsche design..Jag got ahold of it from them...then of course Ford got it from there.
