Best cam for the street both power & sound

if you're at 9.1 i wouldn't personally go much bigger than the 262 cam unless you want it to be more focused on midrange and top end.

more compression, more gear, more stall and you can get away with bigger cams. but then that changes other characteristics of the car, thus the question of: how do you want to use it?

daily driver, blvd bruiser, street/strip, stop light eliminator, etc, etc, etc.
