Here we go, my friend must have been talkig about the road version of Murcielago R-GT altho only 25 road R-GT's will be produced they will have roughly 680Hp while the racing version has 740Hp.
but it does state that "engine is so close to the Murcielago right now, this new 6.5 Liter V12 engine will be mounted in a revised Murcielago that will be introduced after the 25 units of the R-GT have been finished"
Here's the article.

"Automobili Lamborghini SpA is gearing up to expand the line-up ...
At the moment the Lamborghini Murcielago R-GT is getting prepared for the 2005 edition of Le Mans by entering it into competition for the FIA GT Championship, but what's also very interesting, it has been as good as confirmed that a limited production run of 25 units will be sold to the public as a road-going version of this high-power V12 flagship.
The current 6.2 Liter engine of the Murcielago will however be replaced by a 6.5 Liter unit which has been pushed beyond 740 Bhp during testing, production cars will however receive a slightly de-tuned version with a power output between 650 and 680 Bhp to increase reliability. The road version of the R-GT will also use rear wheel drive instead of all-wheel drive to loose weight and ceramic brakes will be mounted, at the moment the first prototypes of the R-GT for road use are being tested at the factory.
It is clear what the objective here is, outperforming their arch rival, the Ferrari Enzo ... and judging by the numbers it should, the 'public' Murcielago R-GT could reach a speed of 100 Km/h in less than 3.5 seconds, naturally this R-GT version will clear the way for the next evolution of the Murcielago ...
Since the Gallardo, with his V10, 500 Bhp, engine is so close to the Murcielago right now, this new 6.5 Liter V12 engine will be mounted in a revised Murcielago that will be introduced after the 25 units of the R-GT have been finished, also it became clear that a GT or SV version of their flagship will be a possibility soon after that.
Naturally the Gallardo will not be forgotten, the Roadster version is still being eagerly awaited, and should be introduced in 2005, the good news is that this time a real canvas top will be used, one that will actually fold away underneath a tonneau, while the rear window will double as a wind block while driving 'topless'.
After the Gallardo Roadster, a more powerfull SV edition with at least 550 Bhp will be unveiled to make sure the closed version doesn't suffer too much of a sales drop after the Roadster is introduced to the market.
There have been talks about a new SUV and a new Espada style 2+2 model, even some models have been seen at the design studio, but at the moment these latter two projects have a low level priority compared with the rest of the model line-up, probably there are further designs for these new models, but right now the two models in the line-up have top priority when it comes to getting them ready for the public, so don't be especting either an SUV nor a 2+2 model anywhere before 2007 or later."
and the site its on, ( a very good site about Lamborghini's)
