JR Motorsports/Karl Performance PRC109H hands down the best high torque full range IMCA flat tappet cam I have every run...! Make sure to get the "H" version (nitride hardened) for a couple $ more, and the Crower lifters with oiling holes on face, and they will last two seasons or more of hard racing. Have never had a failure yet after 10+ years, and my race engine builder swears by them. 3200 to about 7800 screaming stump puller... :O)
