Well, consider this... Look at how high those cams make power.

If you don't prep the block & get everything blueprinted/balanced, whatever you won't be revving TOO high anyway. It'd suck to spend major money on cams that started making power up really high when you won't be going over 8K or something like that.

If you're going to do the block proper, and get a high-revving monster, get cams to match.

If you're going with a basic LS/VTEC get something that makes power earlier.
