On the dyno I use, it would take a little more compression or a different camshaft to get to 600 hp.

However, every engine component is a give/take somewhere along the line. When you increase camshaft duration, you take away from the bottom end of the horsepower and torque curves. When you increase compression ratio, you take a chance of getting into some doo-doo if you run into some bad gas.

With all that being said, 600 is just a number anyway (and it's a relative number based on the dyno). I hardly doubt there's anyone with a Cobra on this forum that could tell the difference between 575 hp and 600 hp at WOT. However, they *can* tell the difference between how the engine runs while they're cruising at 2000 rpm.
