IMO, the main success/failure part of this equation with regards to the "12.00" is the 4 speed.

If the car isn't set up well enough to leave at 5k plus, and hook, and not break stuff..... The 12.00 is going to be a tough task.

This is where I find most 4 speed street/strip combos come up short compared to their automatic/high stall equivalents.
