1988 Olds 98 Regency Specs

I was wondering if anyone could give me direction on where to find engine specifications for my car. I own a 1988 Olds Ninety-Eight Regency. I'm trying to find info such as stock hp, torque, redline limits and such. I have had no luck with my searches so far. If anyone could give me a general direction, it would be much appreciated. Thanks.
