I too have been thinking about the comparison, but would really like to see if GM would make an "X" package for the upcoming Z/28.

Anyway, from what we know (educated guessing) it seems that the two cars would be very evenly matched, but I have to question how they came up with the 524 HP number. There is no way that only a cam, tune, and exhaust would provide a 100 HP bump over a stock SS. Maybe 50 HP (for a grand total of 476 HP), but not 100 HP unless there are a lot more go fast parts going on the SSX that haven't been disclosed yet.

Edit: I think I remember reading something earlier today about revised aluminum heads too, so a Heads/Cam/Intake manifold (high flow) motor could very easily make 100 HP over stock...we will have to wait and see for sure.

If the 524 is accurate I would expect the SSX to have a slightly better power-to-weight ratio than the Z/28 (again, guessing), so I bet it would post faster lap times on most, if not all tracks, than a stock Z/28.

I bet the cost could be higher for the SSX package (+ an SS, of course) than a Z/28, though.

One last final thought that I have already posted in another thread today. If the SSX is indeed only a track car and not setup to be street-legal, then anybody who would have the money for a track-only car of this caliber would be remiss to choose an SSX over a ZO6X. The main game changer for the SSX would be if the cost is only like $10K-$15K over an SS, then it would be much more affordable for a wider range of people.
