What’s up? This is my first post on these forums, but I’ve been checking out the place for almost a month now, and love it.

I was wondering what kind of performance difference I can see from upgrading my camshaft.

This is the camshaft that I ordered:

-Gen III/LS1/LS6 350 Extreme RPM XR269HR Cams
-Part #: 54-414-11 Comp Cam
-HYDRAULIC ROLLER-Great mid-range with superior top end power. Need computer modifications.
-Cam Specs: http://www.compcams.com/Technical/Se...mber=54-414-11

Any rough estimates?

Was just looking for performance differences.

ie: Horsepower/Torque increase, engine responce difference, fuel mileage, that kind of stuff.

well 1 thing who cares about Gas Milage.
The typical Heads, Cam, Intake still gets a 20+ MPG
and capable of 11's very low 12's as is.

LS1's have been dynoing between 380-410 hp w/ cam and intake alone.

You picked a very good cam except they should call it the "346" Extreme RPM

Good stuff Shaggy, thanks for the info.

BTW its for a 2003 Silverado with a supercharger already pushing 430hp

(aint got it dyno'ed yet, so thats a rough estimate from all my addons).

I'll be posting pictures as soon as maybe tomorrow. Should have a video done soon.
