Car made 331 rwhp and 342 rwtq @ All Aspects today... attended a local dyno day to get a number. Not bad for the following mods and the factory tune:

1. Halltech Venom air intake
2. 2003 Z06 H-pipe w/ Corsa X-pipe
3. Corsa Extremes

I was hoping to be a bit closer to the power figures of a LT header/tune car (around 350) just to see if I could get there w/ the factory manifolds by usin the '03 Z h-pipe and x-pipe, but it didn't happen. I'm not planning on spending $2000 (headers + a tune) for another 20 rwhp.

Another interesting thing was the AFR... it was a solid 12.0:1 all the way through the rpm band... so no gains from a tune... or well minimal ones... you could proabably bump timing a little and lean it out a tinge, but for what... 5 horse?

So that's it for now... no more power mods... time for wheels. Maybe an A&A supercharger kit down the road

Cool deal. Whats a stock c6 make, like 340?

Damn, I need to get a V8

does that have the LS6 intake on it already?

Depends on the year and transmission. A stock LS2 C6 (6.0 motor rated at 400 horse in the 2005-2007s) will typically make 340-350 rwhp stock. They're slower than a stock C5Z06 which makdes 350-360 rwhp stock. The LS3 C6 (2008+) makes 370-380 bone stock, but that's the 6.2 liter motor rated at 436 from the factory. The stock 2001+ LS1 is rated at 350/375 and the 1997-2000s are rated at 345/350 rwhp/rwtq
Correct... the 2001 LS1 is basically a LS6 with a 241 head casting and a smaller torquier (mid range) cam. The shortblock is the same other than the cam, it has the same intake manifold and exhaust manifolds too.
