and theres is nothing special about it. They took the C5R engine and threw it in there new C6 vette with a few little changes. Its all in the heads, and the C6 heads are already designed and ported quite well. 500HP from 7.0L + 11.0:1 CR isnt all that amazing to me when a 15 year old TT 3.0L can do it with out any internal engine work.
