i have never ran one in a BBF but,i did run a chet herbert roller cam in a SBF 351. the springs, keepers, retainers, lifters, pushrods and cam all came from herbert,about every 6-9 months it would wipe out a roller and take out the cam,which is BAD,But i would call them and they would warranty it out every time. on cam # 4 they sent me a new cam and lifters and CHET himself got on the phone and told me ''TO NEVER CALL THEM AGAIN'' not that i was going to anyway, this was back in the early 90's so maybe they changed..maybe not.. good luck TRENT
