I think the CAVs are tipping in at around 2,200lbs with an iron block SBF and ZF. 1,900lbs without engine perhaps..... Still, at 450hp (and equiv torque) it's going to take 4.0-4.5 seconds or so to 60 and max around 185mph. And, probably get pretty spooky above about 165 without canards/splitter and a diffuser...
