I want to run an ATI Super Damper on my built straight six with a stroker crank. ATI wants to tack on an additional $800 engineering fee to custom make one with the proper timing indexes because that application has not specifically been engineered and catalogued. Since I can simply use a small snout SBC style damper off the shelf, is there a practical way or a secret trick to applying a new set of index marks on a damper? Has any one of you gearheads out there modified the timing indexes on a damper and have any tricks you care to share? Should I just pay them the huge engineering fee, send them my damper from Canada to the U.S. and have them custom make one for the benefit of all future hot-rodded straight six builders? (Crickets chirping...) Thanks in advance.
