I'm sure that they will, I was refering also to the Fact That Tom Sifton was known for top quality as well as one of his Ace Machinist Design Engineers Dick Hilferty of Red Shift fame, now a days no one seem to know exactly what is what with the Cams that only Hold His Name..Heeey, no offense intended and I definitely appreciate the input. I was just hoping to get a few of the same answers so I could feel that inner shiny glow.
Monte, apparently Black Widow Cams owns all of the Sifton designs, now. They'd probably be able to help.
I remember now....That is where the specks for that grind came from when we was doing your 98" motor...Definitely give the guys at Black Widow a call,they'll be able to tell you what you have. I've got an old Sifton cam with a 106 on the end and on one lobe a J and M on another.I searched high and low and could not find it on any old cam lists.I contacted Black Widow and they told me that the 106 was a master number,not a grind number.They told me everything I needed to know about it,lift,duration,opening and closing on intake and exhaust,and centerline.Good folks for sure.Good luck.
