I don't know, pretty satisfied with mine. Even if it's running pig rich and has some kinks to iron out, it can still dominate the street like the 5.0 always did. This winter has some pretty nifty projects lined up with the old pushrod.
Subaru WRX STI is an awesome car, so are a few other non-american iron but something about a push-rod engine with an aftermarket cam, dual exhaust and RWD makes it way more fun to drive.
I'm also thinking about the LS6 option (plus twin turbo) more and more. I know it's taboo but if I never show you my engine you would never know and as I'm going 10's in a fully streetable car with hardly any exhaust note and 20-25mpg... why would anyone care? Although the new 5.0L engines seem pretty cool too but more expensive to switch over. Anyone want to buy my supercharged 302 which should be near 450 crank HP once it's all done? lol
