LS3 at the strip

Just saw a 1/4 post for the C6 LS3. It's the first one I've seen so far. This guy was an M6 with under 1000 miles. He ran in 84 degree humid weather.

12.4 at 114.5. That car with some cool weather and a few more break-in miles is going to run 11.9-12.0 and the A6's with the 2.73 rear gears instead of the 2.56's should go a couple tenths faster.

The LS3 is the real deal. Better performance, better fuel economy and a ULEV rating to top it all off. Technology is incredible.

That's what I love about the Vette: The best of old and new tech together in one motor.

Come on now, you know as well as I do that 84 is not humid weather. Anyways, the LS3 is one bad ass engine. If my LS1 ever goes out then I will probably put a LS3 in the Vette.

Well if they decide to make another generation GTO I guess we know what engine it will have in it.

2006 Cyclone M/T..K&N CAI.

So how is a 430HP LS3 going to almost match the 505HP LS7?

I would think 12.4 is on the low side of what will be average for these cars.

So I read an article in GM high tech performance. They commented that GM had just won a patent for 3 valve cylinder heads. But that they had heard talk of dual in block cams. That's interesting, right?

Well that tells you that GM knows what they are doing and they do it well. That also shows that the old, dinosaur pushrod engine can still do the job with fuel economy and performance. OHC tecnology not bad (is just as old as cam in block) but still the simple desine of the pushrod has proven itself time and time again. The pushrod helped save the Corvette now the Corvette is saving the pushrod.

That 12.4 will be at the bottom of someones list here in the near future soon as more and more people take them to the strips and dip down into the mid to low 11's, if a LS6 can get into the 11's the LS3 will have no problem. I'm glad to see that the Corvette is still the dominant car on the streets. In my book the Corvette is the worlds fastest, oldest, street leagal mass produced car.
