174/177 supercharged small block, where to start?

Are you running 6 rib pulleys or 10 rib?
These are 6. I’ll see if I can get my 10 rib system to work, once I have everything in hand. It’ll be a little bit, the 10 rib idler is on back order.
But I’ll be pulling the motor out of my truck and I’ll swap this one in. Gotta build my in tank pump fuel system for that thing.
