I would put the cam in at about 115/116 cl and it should the pressure down. I would say in the 190s range.

hmmmm sounds like a bit of compression to me,does this engine have steel rods? or aluminum?
Whats the lenght of the rods center to center?

The cam sounds ball park if thats a nitrous cam.

Spraying vast amounts of nitrous in a steel rod engine,especially 650 hp of nitrous I wouldn't advise,,but some guys like to live on the edge.

Now with custom aluminum rods maybe you can go with that amount of nitrous.

Just do good bearing maintaince on the rods and mains would be my advise to you.
