This is not a ZL-1 with 9:1 compression.
If this is an LS3 10.7:1 compression you are going to be limited to about 9 psi boost which will make around 560-580 this can be achieved with a 3.4 pulley.
If L99 you can run about 10 psi boost due to lower 10:1 compression which will net you 530 ish RWHP.
The 2.97 it too much for either engine and belt slip even with griptech will be a problem.
IAT will be a problem as well with this supercharger without further modification.
Did you see my note about correct plugs for your application, NGK TR7IX
