Ummm. I think there are plenty of people that would like to argue that a 302 wont make over 400hp. Also, you won't see any NA 2V 281's running 11's in the 1/4 mile. The 4V is another story of course. Yes, stock for stock the newer 4.6 GT's are better. That's what advances in technology will do. But upgrade a 302 to aluminum heads, which the 4.6's have, and see which put's out more power.
