NIssan unveiled the 2010 370Z Fairlady

Nissan threw the gauntlet and revealed the 370Z before their scheduled unveiling at the LA Auto Show. Showing what for months everyone had speculated, guessed and scooped, the 370Z did not surprise disappoint much, as it looks exactly like a 350Z, but looking tauter and more compact. We'd have to wait for official specifications, but as a tradition of Nissan's Fairlady range, 180SX is 1.8ltr, and so on till the likes of 240sx, 300zx; this new 370Z had a 3.7ltr V6 engine pumping out probably a healthy 300hp for starters? What's your speculation?
