For myself, I would go with the 6. Nothing like the sound of dual exhaust 6. Use an X pipe to take the rasp out. You won't make the HP with 6 holes that a V8 can provide. For syreet driving torque is what you need and the 6 will provide that and get good fuel economy doing it. On the street you can suprise a lot of V8s with a well built leaning tower of power. On top of that you have something different in the row at the Cars and Coffee meetup. Too many cars had Chevy small blocks stuffed in them. Now it is LS engines. Zipper engines making transvestites.
