304, legally I could shoe horn in a LS1 (350 for those unfarmiliar) Not with a hint of trouble from any one at the MVR. But that still costs lots of money, which I lack. But if I did have money I would go the lexus 8 with a couple of turbos hanging off it for sure.
I think the V6 I had was just a dud. My exgirlfriend's parents have got a VP commodore and it's clocked up well over 250 000kms and they use it to tow the boat with and it still frys the tyres ( so her old man tells me).
All in all, there still crap.
It's good to see that people (some not all) still think in the same frame of mind, go the 8.
