How does this zz572 620 HP perform on a open road course? I know big blocks are heavy, but this one is all aluminum. Anbody get on the track yet?

572 block is iron, only heads and intake is aluminum. Have not had mine on road course so I cannot tell you how it would do but I would think a properly setup car would do ok.
