the 4 bolt will hold more hp and higher revs if built correctly
but the 2 bolt can be made stronger if you spend the little money and have splayed 4 bolt caps installed

The two bolt is fine for the street.
If your going racing and running over 6000 rpm all the time then ya want a 4 bolt.
I think a two bolt should be good for 500hp if your machining is all good
But then hey 4bolts can be had for the same price as a two bolt.
