I have a 2001 Aggressor. I can't tell you the exact performance with a 496 Mag. , but I can tell you that it handles chop very well due to the 7 foot beam and 24 degree deadrise. Mine is extremely quick and nimble. Give a call to Sunsation, they should be able to answer any questions about performance. If you can get the hull ID number off the back of the boat you are interested in, they should be able to tell you everything about that specific boat build.
