Crank hub question

Okay, thunder racing sells two sizes of crank hub. Here's the question; I have a 97 lt1, but I am using a 94 serpentine setup. Is the hub specific to the crank or the serpentine setup? The timing cover and distributor are from the 94 (spline driven). The crank is a 97. Do the different hubs affect the depth of the balancer?

I am mid build prepping for the swap. So a quick response would be awesome. BTW, I made a youtube channel and am posting videos of the swap. Right now it is just part and block vids. I'll post more as I go.

Re: Crank hub question

Ok, I found out that the OBD II hub is shorter due to the relict or ring.
