picking a cam IS NOT GUESS WORK,BUT IT DOES REQUIRE YOU TO DO SOME HOME WORK!
the cams rpm range must match your intended use for the engine without going over the engines REDLINE (on any non-all forged chevy v-8s thats 4000fpm of piston speed and even on all forged engines its best to stay under 4500fpm of piston speed)
next the cam must not have valve lifts that cause clearance problems or have lifts much higher than the cylinder heads ports peak flow lift points,the dynamic compression ratio must be in the 8.0-8.5 range for best power and the the cams overlap must match its intended use too.read these posts.
