I researched it trying to find which engine of the day would have Horsepower closest to mine, and the 350 was rated between 290 and 300 Horsepower. The 302 was out and the SS in 2010 blows away the engines of 1969 in everyway (fuel economy, ect. ect.). Yes the "purests" will have a problem with it, but I don't care. Just trying to show the love for our older brothers. Enjoy.
