I'm trying to get my run-out in spec prior to throwing the engine back in.

I have a brand new Quicktime bell,

Side to side was nearly perfect, but up and down has a ~.024" TIR!!!

Is that a little excessive for this "spun metal, Perfect bellhousing"????

I wondering if I should send it back to Summit for another one....

I will need .021 off-set dowels such to make it within the .005" spec!
