It would seem the LS3 does not use VVT. The increased bore and some other intake and exhaust tuning was responsible for the bump in horsepower. Redline also increased slightly to 6600 RPM.

yes i believe so....we dont expect to see that incorporated til 2009 at least

and as far as the dual-mode exhaust goes....all i can say is i definitely wont be needing it....aftermarket is the way for me!

Thats an awesome motor! Wheres' GM performance crate motor?

When the time comes I'd like to drop that warrantied motor in my car.

Thats a perfect motor...IMO..

Slap it in the c5 with headers and call it a day.

Any word on the cost of the crate motor? That would be awesome.

I think the ls6 was 5500 plus installation.

I'd imagine the ls3 should be the same...

good luck to anyone trying to get that to hook up on the street....i know it is frowned upon but 99% of the racing i do is on the street

so what is the point of all that horsepower if you are a street racer and all you do is lose traction at all speeds?

not to mention the look on a the guy's face who just bought a SS corvette after i beat him in my h/c/i LS3 will be priceless....traction is everything and with the supercharger on the future SS being a "roots" blower which produce alot of low end torque will certainly have traction problems

but you would only have to worry about this is "IF" you street race :thumbsup:
