1. When a team drops 25-30k just on component R&D the difference of a grand, maybe two for heads components does not seem like much.
Also these teams seem to do just fine with the hydraulic adjustor valvetrains too. (my main point) They see extended, repetitive high rpm (at least 8k) and are making over 300 crank HP from 2.5L's

2. You are failing to figure in the rpm point at which upshifting will leave you and the fact that TQ rapidly falls off after 6500rpm.
Even with custom cams set (like I previously mentioned) specifically designed for high rpm use (I.E. losing most streetability) you still would not want to push the limit much past 8k anyway. (say 6000-8500 rpm powerband) Plus anything below that would suffer tremendously.

I still don't see this being steetable and you would likely want a steeper final drive (like the 4.5 available) to keep the rpm up.

You are now talking about spending at least 3 times the cash outlay to make 10% more peak power and mainly because the CR & redline is so high.
The power band would be much narrower and peakier as well.

The funny thing is that on anything but a long open track a regular 3L hybrid would be faster as it would have much more usable power.
Also this "LS" engine built to regular specs would be comparable in power to any regular hybrid just cost twice as much. Also don't forget the fact it has only one set of "moderate" cams that are available & getting around the VVT electronics. ($$$) This basically mean that even to use the valvetrain's better rpm ability you NEED all the high dollar custom parts.

This all brings us full circle to my original post.

NOT EVEN REMOTELY WORTH THE MONEY. I am very curious to see the final power curves and the final cost analysis myself...
