Not Ranked
Two 450's wouldn't cut it. I would go with at least 600's, if not some 725-750 cfm carbs. I've ran (2) 1850 style 725cfm carbs on a 428 with a Tunnel Wedge and it loved them.
Your heads and your cam are going to be a bottle neck. Don't expect the peak hp rpm to be much higher than your previous combination.
