There used to be a very comprehensive set of buildup photos on the web a couple of years back - not sure if they are still around but it is beautifully constructed!
The only 'mistake' they make IMHO was the nose - just makes it look like a Firebird!!
Having said that they would not have run the numbers without it. But maybe they could have sone a different front end that was still aerodynamic.
Top notch
BTW, I notice that TT page says it has a new 358 cubic inch R5 Sprint Cup engine. I know it definitely had the 4 banger before as you mentioned Steve (which was basically half a SB V8), so looks like it now has an eight....
