Can you get to 400 without turbo or super-charger

LS7 is the only stock motor I have ever seen blow...

Meh. It's a pretty much maxed out N/A motor, but makes a good twin turbo motor.

FWIW, there's a reason the new LS9 isn't the 7.0L, but the 6.2L heh. They found that under boost, the LS7's sleeves didnt take it quite as well as the LS3's did. So, rather than run lower boost without much room to expand in the LS7, they decided to go with a REALLY strong forged 6.2L LS3 setup boosted to high heaven. People will swap the pulleys on those and make north of 700 HP in no time, it'll be a joke. Thats not to say that other LSX 427's cant handle it though . Here's my buddy from Omaha's current project: http://www.neufamily.org/images/67novagallery/. Some people who read Hot Rod magazine will recognize him as the guy who had the big single (eventually becoming a TT) Blue Silverado that won the first Drag Week, and then won again the next year in a different class.

As for the LS7 being weak...the stock valvetrain in the LSX series has usually been hailed as one of their strongest points, so I'm a little surprised - its always possible that particular one was flawed...as you said, the 2nd's holding strong right? But the other guy's right - look at anything powered by a Wankle - Apex seals what? May as well become an ASE certified mechanic before you buy an RX-7/8 heh...

And Ninja - no offense taken, my other message board thrives off of its Gloves-off section. I probably went a little overboard anyway. Maybe I just learned fast that street racing is really overrated, I don't know heh. High horsepower cars were really cool to me at one point...now, I see them as purposeless unless they can actually put the power down to the ground with a reason...
