GM Posi ?

I'm gonna upgrade from an open to a Posi or Limited Slip. I have my eye on a GM 8.5 " 10 bolt 28 spline for sale on Ebay. My 355 is basicly a 1970 LT1 pushing about 320 HP. The gear ratio is 3.73 The car will be used 90% for street use. Can I get buy with this GM posi or should I set my sites higher?
