OK made post last night on how to remove spacer on front of damper.... thanks for the help, it was just a very close machined fit into the front of damper.

Keep in mind I'm new to LT1's...... The book shows the damper coming right off after the removal of the 3 bolts. In looking at the ATI damper it appears I will need a standard balancer puller to remove, is this correct??

Also, I'm under the impression this is a NON keyed damper. My plans are to remove damper & distributor to repair leaking seals. Are there any precautions I need to do as far as ignition timing goes?? Very familiar with older version TDC method when reinstalling distributor, but what about this front mount distributor stayle?? Does it matter what position the damper goes bak on??

Thanks for the input!!

 

If the damper hasn't rusted around the crank snout, then often simply removing the 3 bolts is enough to pull off the stock damper. From the factory, it's true that the crank/hub is not provided with a 'key'. The slot is in the crank (I don't recall if the hub has a keyway or not). Certainly with a blower, if the ATI is not already keyed on the crank, I would put a key in there.
