I was having a 470 stroker built for my Dart last fall and before the guy helping me build it (a relative) and I could finish it he passed away. Before he passed we had installed the crank, rods, pistons, cam and timing chain. I haven't touched it since he passed but would like to get out in the garage and try and get it finished. Not sure if I can do the remaining work on my own or not but that's another matter. For now I have a question about the timing marks on the timing cover and on the damper. With the #1 piston up to where it is flush with the surface of the head, when installing the balancer on the crank the timing marks don't line up. The TDC mark on the balancer is aligned with the 10 degrees BTDC mark on the timing cover. I am using the stock 400 timing cover that was originally on the motor and a Summit C-4279 damper. Is something installed incorrectly, am I using the wrong damper or is this typical of aftermarket dampers?
