how much hp, tq will 8.25 take

Thanks for the replies, it's in a 70 b-body at the moment shipping to New Zealand in a couple of weeks.I have a 408 stroker about 500hp here in NZ but may build a 470 stroker as i have a 400 sitting here and put the 408 in my 68 dart.It will mainly see street use with a few trips to the strip cheers Brett
