Vacuum

I'm trying to figure out whether or not I will need to run a vacuum canister or not. With the Trick Flow stage III cam (.574/.595 286/298 adv. dur. and 236/248 @.050) will I have enough vacuum to run power brakes and power steering? Also what about a vacuum secondary carb? I am looking at a Speed Demon 650cfm electric choke, vacuum secondarys. If I do need a vacuum can are there any suggestions for which one to buy? This is a carb'd motor so there will be no computer or unnecessary wires, fuses, solenoids, ect. Any help would be appreciated.

haha, short answer - no.
sumimt racing has a nice selection.

So if I get a vacuum can for my power brakes will I have enough vacuum for my steering and carb or do they even need any?
