I think I'm in the "couldn't care less" camp as long as it's a V8, makes at
least 400hp (or will do with breathing mods) and generally goes like stink. Personally it's the 0-62mph and top end numbers that count to most - not the "My car has 14trillion hp" - that's what us europeans call "Pub talk". It's completely toss.
Besides, mines gonna have a supercharger either factory or otherwise!
