350ci LS9 info?

Ive got a 1971 GMC Sierra Grande 1500 with the LS9 option 350ci and i know only a little about it. I,m pretty sure its 4 bolt mains but other than that i dont know much. What were the ratings for it in 71? could it be a high nickel bolck? any other info would be awsome, Thanks

No guarantee on the high nickel block,but should be rated at 255 hp. More than likely a 4 bolt also,but again no guarantee.
