I think that's about right with a cam and headers. Mine would peak about 9 with the 3.75" pulley up top but it made a little less down low.
I just swapped the 3.5" pulley on and I haven't went wot yet because it is cold but it is really easy to get to 8psi mid range with a little over half throttle so I think it will make good boost as long as I don't have belt slip.
Safe is a opinion. There are lots of people running a smaller pulley on a stick motor but it is a risk just like your current setup is. It will probably be fine but no one can say 100% because you can have motor problems with a bone stock car.
I wouldn't think twice about going to a 3.75" pulley though. I have one I'm going to be selling in about two weeks.
Who is tuning the car? That is the biggest factor in the question of safe.
