Inliners International Forums General Discussion Engines Engine Torque Rating for 261 Chevrolet

Is there some book, webpage or other source for the horse power/torque curves of a stock 261 Chevrolet engine. The only source I've found is the Chevrolet restoration pack. I found the 216 and old (Babbit bearing) 235 ratings in my 1952 Chevy restoration pack. Problem is, I'm restoring a 52 and am puting in a 58 engine. I don't have a 1958 vin to get a new restoration pack. Do any of you by chance have one? Is there a webpage with this info?

Thanks
