I received a book on Muscle Cars for Christmas and found a two page layout on the 1969 Hurst/Olds. The book is saying that they were rated at 380HP and 500lbs of torque from the factory, but I think these numbers are way underrated considering the quartermile time listed of 14.03@101.

Has anyone dyno tested an origionally restored engine for this car?

 

I cant remember were i read it but a mag had ba test dyno on the basic muscle car motors and how close the stock rating was to the real numbers and witch ones were under and over rated the article stated teh dr olds was right on the money for the motor they tested I think it was a 70 455 w-30 .
