Metal Wulf brought up the question about the XE262 Comp Cam so I got to looking at CC website for more information on the cam. After doing some looking I found out that the XE262 is there most powerful cam as far as torque is concerned in the XE line. This is on a standard engine rated at 9.25:1 CR. What would a 10:1 ratio do to the HP and Torque numbers? I am wondering about my HP/Torque numbers.

Here is the graph that Comp Cams has.

not a lot,maybe 1 to 1.5% over all power gain.

Eddie,
Thinking about a cam swap already?

No, just wondering where I stand with what I have got. I was just wanting to know what difference CR made in the overall scheme.

The gains in HP/torque would probably be around 15-20 each. Run a simulation in DD2000 w/ your cam and engine specs to get a better idea though.
