I know the stock crank/hub didn't use a hub. Since this piece is neutral balance I see no reason for a key in this one either, but want to make sure.

I also don't know which way the harmonic damper goes on the hub? One side has the dimpled holes, and the big c-clip looking deal, but if I face that towards the back of the engine, then the timing marks are on the engine side of the damper, and they kinda look backwards. If I install it how it looks like it should go according to the #'s, then the dimples face out as well as the c-clip. is that right?

Also, I don't remember what my stock hub/damper looked like, but this aftermarket one has the timing marks like I said. Will I even use those? If so then I'm going to have to make sure that this hub & damper is lined up to SOMETHING...

You will not use the marks on a LT-1 and the hub can go on any way.The weight will only fit the 3 holes in the hub one way,usually there is an arrow or a mark.As far as front or rear check it with the belt alignment or the groves in the pulley.
