Hope everyone had a good Thanksgiving and weekend!
Quick little update, I went ahead and pulled the ATI damper back off to do something I should have done in the first place. Per ATI's instructions, you need to measure the crank snout diameter and the bore diameter of the damper to possibly hone the damper bore to achieve a .0009 - .0012 interference fit on a 1.250 crank snout. The damper comes with a tighter bore tolerance out-of-the-box than factory due to it being a race application, so this is a necessary step to make sure it seats all the way on the snout and against the crank sprocket. Skipping this step can lead to a snapped crank snout. I mic'd my crank snout multiple times at different angles to get an average, but unfortunately I do not have a bore dial gauge, so off to the machine shop I go tomorrow to have the damper bore measured and possibly honed.
Did it seem to be fully seated the first time? Yes. The car idled fine and the belt was straight. But even a hair's width gap between the damper and sprocket creates a shear point and potential to fail. So why risk it?
Bent the $h!+ out of my cheap balancer puller trying to remove it the first time, had to go buy a new one, which got it off easily 😅.
Random shot of my new 3 core radiator and some amsoil for the next oil change as well.
