I think that is Milano or late GTV6 2.5 Engine, I think the finned with Block is the late 2.5, finned with Script is the 3.0, smooth with script is an early 2.5. The intake has been modified though, the port for the idle adjustment has been blocked off. It might be because the early GTV6s had a slightly different version of the L-Jet system.
