You will not be able to achieve 550hp with just heads and cam man, sorry to say but you will need a whole new engine for that.

agree, as far as full bolt ons heads and cam the most hp i've heard i think it was around 450's - 470's whp ( i could be wrong)

Either need to build a motor with more cubes or just get a head/cam set up and you can get around the 450's and add a little nitrous for when you wanna be 550 plus hp.

There are some HIGH STRUNG 346's making over 500RWHP. Wouldn't want to spend much time on the street with them.

It depends on if the goal is 550HP at the fly....or at the wheels.
Flywheel....it is possible.
