174/177 supercharged small block, where to start?

Picked up a 1190 belt today to run the smaller pulley, what a world of difference it made, however I'll need sort out the thermostat housing and rad hose better as it blew the hose off on a hard run and made one helluva mess.
Post pics of your setup if ya can. Odd thing about your radiator hose blowing off, what’s that about? I couldn’t find an 1190 belt so I made what I had work. What’s the PN?
