New Cam and headers installed
I took advantage of one of our forum sponsors install packages. Horsepower addicts is running a Cam install on this thread http://forums.corvetteforum.com/c6-t...-delaware.html
Josh is the owner of Horsepower Addicts and installed my kooks 1 3/4 headers and x-pipe with cats with the Cam install onto my manual 07 LS2. I got the headers (and a great deal) from Maryland Speed and they shipped them for free to Josh's shop where he held on to them until I could make it to my install appointment.
Work done:
1 3/4 Kooks headers & xpipes with cats
231-239 custom comp cam ( I didn't want anything too aggressive)
Ported throttle body
Dyno tune. Max power 406.28, Max Torque 378.76
The vette sounds great compared to stock, impressed with the work done, and Josh was very helpful answering questions and even worked late into the evening on my install since I drove out of town to get all this done. If anyone has any questions feel free to PM me.
Here are a few pics Josh was kind enough to take for me as he was performing the installs.
Kooks headers
Cam
Dyno tune
New Exhaust hooked up

I bet the stock intake manifold is really holding you back on power.

I'm running the same cam, but have Kook's 1 7/8" headers, Corsa Sport axle back and a ported 90 mm FAST intake. I've made 452 rwhp on a couple of different DynoJets and 438 rwhp on a Mustang Dyno. I think a few more tweaks on yours and you could take full advantage of the cam.

seems like it's an LS2. is that actually low for cam and headers plus tune---406/378? wouldn't baseline be in the 350/X? just asking, don't know the answer or why it's considered low.

Jacking pucks or not you do NOT lift a corvette from those spots. That is lunacy. And this is a forum sponsor?????? Good luck getting business with that photo floating around!!!

You two should take a closer look at the picture... The pucks are on the arms of the lift lifting the car from the correct lifting points. The pads on the ends of the arms are over an inch away from the floorboard. I have personally lifted hundreds of C5-C6's and know them well.

406 from a cammed, manual LS2 is quite low. It's not like he put a baby cam in...231/239 is pretty healthy.

Stock LS2 mufflers are restrictive. I measured as little as 2" ID in the set I cut open. Also 07 factory intake/air filter isn't all that good. Bet you will see a lot better numbers with those opened. Of course then get a re-tune.

This car has a BBK alluminum air intake that sets the filter above the shroud.Stock untouched ls2 manifold, stock pulley, hardened 7.400 pushrods(verified preload), flowmaster mufflers, and heavy 20's out back.
There is 30+rwhp to be gained with upgrading some on the bolt-ons. The owner did not want a huge cam. He wanted a car that drove great and had a noticable idle. Drive-ability is perfect. Zero cam surge at 1100rpms.

Ah very good. Ya, there's a solid 30+ across the entire range with a proper manifold on the car.
Zero surge with a 231/239? Not even a little buck? My 230/238 has a little hiccup around 1400 but I've learned to drive around it. It certainly wasn't a deal breaker.
Any sound clips?

My 240 hiccuped around 1400 also. No biggie, worth the 460/426rw.
@ HPAddicts, 231/239 is by no means a small cam either. I agree about and initially mentioned those Crays probably being responsible for sapping some HP. That said, the so-so BBK and so-so Flows + the wheels, + no UD pulley + Kooks + a conservative tune... I can see the current numbers adding up.
The BBK and Flows aren't the best performers, so I'd subtract maybe 6-7rwhp for that combo over something like a Vararam/Halltech & straighter exhaust, the wheels may be eating another 5-7rwhp, and the lack of a UD possibly another couple. Kooks tend to be hit/miss from my experience.
With a more common assortment of parts and stock wheels, I'd think the same car might make 420/390, which is ballpark for a stock-manifold MN6 LS2 car. So for me, I believe your tune is just fine given the parts.
