Or the best option would be a 426hp LS3 automatic with the gas guzzler tax. Give us the choice, please!

FYI:
Torque difference is a whopping 13 lb-ft (insignificant) ergo, the L99 has PLENTY of torque. It also is capable of MUCH more power when modding than the LS3 due to the very enhancements (cam phaser, slightly lower compression *blower anyone?*) you claim are robbing it of power and making it slow. Making broad statements using an insignificant sample size is never a good idea.
From WIKI:
Differences w/ LS3 Engine
* L99 used in automatic version SS models. LS3 is used in manual version SS models.
* L99 produces 400hp/395lb-ft tq compared to LS3's 422hp/408lb-ft tq.
* L99 camshaft is different -- having a little less duration and a little less lift, both of which give the engine a smoother idle.
* L99 has a cam phaser and, to get the additional piston-to-valve clearance required when cam phasing changes, the pistons are different parts having valve reliefs machined into their tops. The reliefs lower the compression ratio to 10.4:1.
* L99 PCV system is different having its oil separators in the valve covers rather than down in the valley like the LS3.
As far as getting beat by 300hp mustangs goes? If one beats an L99, then either the driver had issues driving or the rustang has some pretty serious mods. Maybe it's a bottle baby?
