Probably neither. Both are at opposite ends of the spectrum.
Nothing you do to a 6 will give you the stump pulling torque of a Big Block.
As the question is from someone who has owned both, the answer is probably
another car all together. Maybe a new ZO6?
(Not a BB, but might be the middle ground he is looking for?)
Or for the same $$$$ as an older Dodge or used NSX, a 2-3 yr old ZO6 might work out ?. A (3) liter six cant give you the "slam you back into the seat" feeling of an engine 2 or 3 times as large. Nor should it.
On the other hand, what else can give the high winding, go-cart sensation of a set up NSX?
As far as Vipers go, they are seen in my area much more than NSX's.
And to be honest, they always kinda look out of place. :tongue:
Quite the stand out, as they go putting around silently at posted speeds.
Buy a car designed to give you what you are after.
(1st you have to know what you are after?)
This really is a foolish question.
Cant believe I even replied............. :redface:
If you dont know what you want, drive some more cars. :biggrin:
It will come to you.
