Best guess on 416 motor

Hi guys I'm building a 416 stroker and would like a best guess on ET./mph
3200 lbs Duster, 4.56 gears, 28" tire, 4200 stall, 727 trans.
340 block with a K1 crank {4" stroke} and rods, diamond pistons 10.65 compression. Heads are Indy T\A that have the full port job, told they flow 306 cfm on intake, TTI headers 1 3/4", SUPER VICTOR INTAKE with a 830cfm holley on top, Solid cam with .590 lift .263 @.50in .268@50ex. So give a idea what this will do.
