TI ignition part ID

[AMANOCC]

Distributor shaft for TI, pole piece looks different than I have seen....what is it's application?

[John Brown]

Looks like an aftermarket pole piece that has been pressed up on to the original cam. I think Borg Warner had kits that were made like that. Maybe others too.

The advance plate is from a LS6, as well as others I am sure.
