Well it'd be nice to see more of the sled than a glimpse of the hood and just enough running board to tell that its aftermarket. BUT, seeings I'm 2 weeks late and it hasn't been announced, I would like to guess 414 lbs, since someone already took my answer that would've been 2 lbs heavier.
Springer claimed that when him or Winter built the IQr with a VE tunnel and 15X" track they all fell between 415 and 420 lbs. His might be lighter than that as I know you lose a lot with a bare, aftermarket hood. Was gonna weigh the difference on mine...
