This is just a guess but since the net hp ratings started in 1972 the 454 was rated at 270 to 275hp. The 70 version had a higher compression ratio so I would say it would put out 300hp in stock trim.

Check out Markus' website (Zwede). It's a 71, but close enuf to a 70. He has dyno sheets stock, and also showing the improvement after several mods. :)
