Any experience with these cams?
Comp Cams XS268S
Comp Cams Magnum 270HR
Comp Cams XR276HR
Anyone have any experience with these cams, particularly in a SBC?
Thanks in advance!

Re: Any experience with these cams?
I'm running the 270H in a 406 with 10:1 compression and AFR 195 heads. I love it! Awesome to 6K RPM...has a good idle at 800 rpm and a good vacuum signal, 15 degrees, which is great for q-jet metering and pwr brakes. I'm also using the comp cams roller tip rockers. The valve train is a little noisier than stock but, the trade off is obviously worth it.
Good luck

Thanks
Is that the hydraulic-roller version, or just the straight hydraulic version? Straight hydraulic? I'm looking into the HR version. Do you think it has a good flat torque curve? Where does the power come on?
I'm also planning on running a Q-Jet. Looking for a cam to swap in place of my big 292H.

Re: Any experience with these cams?
Sorry MM,..yes, I have the flat-tap 270H,..not the HR. Regardless, I'm happy. I also have a flat-tap 280H in a 496, and it's perfect for what I want,..a car that idles, pulls vacuum, but shakes the asphault when called on.
Good luck with your choice!
