any of the "tork cams" would be a good choice 260 to 272 duration i run 268 in my 460 and 272 in my 501 and am happy with the "driveability" smooth idle,ect pay close attention to the cam makers recomdations for use and rpm too big of a cam will cause all sorts of headaches and needed up grades [rockers,tork converter,intake,exaust ect another thing thats "old school" but works for these motors is useing a timeing chain/gears from a pre 72 429 that puts the timeing straight up instead of 6 degrees? retarded for emisions being there done that and am thinking of doing it again for another 460 i am building hope this helps regurds joe
