Am looking for a quality replacement 9 way ajustable timing chain set for big block roller cam race motor. Currently have a Cloyes unit with a thrust bearing that I am done trying to work with. They dropped the ball with that one. I remember talking with Cab about that one. Not sure what his solution was. I will be using a thrust button or Mancini thrust bearing and an Indy cast timing cover.Trickflow has one listed as part# TFS 61678525 and was wondering if that set was up to the job. Would like to hear from all who have had good results with any others also. Thanks,Bill
