Which pulley for my D1?

Hey guys, looking for a hand again!
Im running an Lt1 with no mods other than full exhaust through pace setter long tubes, 42# injectors and supporting fuel mods. I recently acquired a D1 (not D1SC) kit for my car, with what appears to be a 8.5" crank pulley (measured diamater from top of grooves. Since the D1 has a 4.44:1 step up which is higher than the D1SC, what pulley should I be using to get 5-6psi? Im at 1100ft elevation, if that makes a huge difference?

I know the internals on the car wont last, and i do fully expect them to blow up in short time even at low boost. I will have a motor being built this summer, so please avoid that being a main concern in your post. Just need a blower pulley!

Thanks guys.

I'd say a 4.25 pulley. I think thats the biggest you can go.
