Impressions:

Simply bliss. It feels like an entirely new car. As soon as you start the car, it feels and sounds like it has the power to back up the looks. It shakes your entire body. In normal driving it's quite tame and drives just as smooth as stock. Currently, there's a bit more jerkiness and stutter when you take your foot off the gas in gear, but I'm hoping it's something my tuner can tweak. Getting on it, it's incredibly responsive. I figured there would be a bit of lag, but really it's instant power and it just keeps climbing. Right around 3k it starts unleashing and really opens up. It's an incredibly addicting sound and it just keeps getting more and more glorious as you climb the powerband. It pulls like a raped ape from 5k to redline. It simply is...incredible. There's a few tweaks I need to do yet, but my tuner will be getting his hands dirty on Thursday. I plan to re-dyno at the shop I was at when I was near stock to help get a better comparison of the gains, but numbers aside I'm absolutely ecstatic with my new car

I'm at work so I can't see the pictures. Sounds like a really good build, the Z06 is just a monster with a cam, it really just makes it a different car. I'm just in love with mine since the cam install. I'm really happy for you, I'm sure your just looking for a reason to drive it. We need a video of your idle sound, all the members love to hear a cool cam.

call me crazy but isn't that REALLY good numbers for stock heads? Congrats man! Other than the tuning, did you do the work yourself? If so....give yourself a pat on the back!

I have video near the end of the first post!

That's what I thought as well - definitely one of the higher hp cam-only, stock head cars I've seen. Doug Rippie Motorsports did the install and tuning - I don't trust myself doing internal engine work haha. They did an incredible job and I'll definitely be back!

Impressive results but nothing out of the ordinary for a large cam and 243 heads.

Sounds SICK!

Yup, I got 04 GTO with stock 243's (PRC .650 springs) off of a 03 Z06, and with cam/243's made 386rwhp & 374rwtq. Thats with STOCK mani's and exhaust. K&N cai is only other mod.

Best friends 03 Z06 made 464/436, waiting on his computer to get back from texas speed with a few tweaks and a larger maf. It was patriot heads/torquer v.3/headers/borla/fast 102/ 90mm electronic tb, bbk cai.

But congrats, great numbers and it looks gorgeous. Love the wheels.

I didn't do the install. I'd say this would be your best help: http://www.ls1howto.com/index.php?article=23

Thank you!

You NEED to get the exhaust addressed...it's a night and day difference and I'm quite happy I did both at the same time. Now I definitely need to address the intake! Thanks for the kind comments.
