Upper Pulley for B&M 250 Blower

I'm having no luck finding a 3" upper pulley part #155192 for a B&M 250 blower. If anyone has one or knows where I can get it PLEASE let me know. The motor is sitting on the dyno right now.
We need more boost, I went from a 502 to a 540 block, so we lost a fair amount of low end boost. Hopefully someone can help. thanks
