clutch size? best street clutch

We are installing a dual friction 10.5" clutch from South Bend Clutch..I did tell Peter @ SBC that we were going to run this car 90% on the street and 10% drag strip..and when it does see the strip..we may be side stepping the clutch at 5000 rpms..and he said do it..
Peter said that we would love how the clutch hold not only on the strip but also the street manners.
