Probably more like 5-10hp if you don't listen to the marketers. I've never measured it though. 1.7 is the stock ratio on an LS1.

Stock LS1's already have roller rockers. They do not have the roller tip and that won't free up that much HP. The biggest gain is from the roller fulcrum, which you already have.
