PS issues + general acc belt problem

[Mrturner1]

So this isn't really a pressing issue because the truck still drives fine, but it's annoying and will get old fast. Here's what I got...

1970 c10 LWB

355 w/10.3:1 comp 4 bolt
RHS 170 heads 2.02/1.60
Edelbrock perf rpm
Holley 750 DP 1" phenolic spacer
Comp cam .495" lift 236@.050" on a 106 LSA
Long tubes 3" exhaust Flowmaster 10's
TH400 3000 10" stall
12 bolt 3.73 mini spool

Ever since I put the 10" converter and the new cam with a tight LSA, this thing revs in the blink of an eye. We're talkin idle to 6k in an instant, which is awesome except that my belts can't keep up with the pulleys, so when I rev it she squeals a little real fast, and my power steering pump (stock old pump) won't stop chirping when I turn even at low rpms.

Are there high performance ps pumps that will fix this?

And what to do about the belts? <---not as pressing of an issue it's barely a squeak when I rev it
