Good afternoon. Have run Roll Master timing chains for years with great results. Freshening my 738 HP combo that see’s quit a bit of street duty. I was at builders the week after disassembly and chain was in really bad shape. Combo has maybe 30 passes 1/4-1/8 passes and maybe 500 miles.
Any feed back or has anyone else experienced this issue? Builder is thinking harmonics? We will be replacing dampener with a ATI aluminum and bearing look like new but for a little dirt scratch in #4 main bearing.
