I have a 96' 502mag in my 29scarab. Its been bored to a 509", the stock heads have been ported and roller rockers where added. It also has a side mount whipple making about 5lbs of boost. The charger is getting old and the computer is out of date. My qestion is can I make around 600+hp with aluminum heads a new cam with out the charger or should I just get a new whipple? I have heard that the intake system is the limiting factor on these motors. I'm just looking at my options. Thanks.

AL heads and a cam will get you to 600hp without the SC.

Thats what I was hoping. Save a little $ and more reliable. Thanks.

Just for the record, you can make 750-800 hp with the stock intake, as long as you have aluminum heads and a good cam at about 6-7 lbs boost.
