The 3L UIM hasn't been used yet for an S/C that I'm aware of. Everyone is using an SVT U/LIM thus far. You would probably need to fab an extension or another tube all together to make it work correctly. For a block you want the 2001 and up if you're going to use all the 3L pieces including manifolds. Rods would be a good investment option. Contact
nikolas@durectecperformance.com and he can hook you up with pauter rods. The CR I'm running is 10:1. So far I only know of one motor that is dropping the CR on a 3L and that is Jim Hahn going to 8.5:1. Everyone else is using stock pistons though I had mine cryo treated.
Thanks,
