454 big block chevies were not released for production until the 1970 model year . So the one in question is not original equipment and did not come in the car . If you take the casting numbers off the block , you (or someone else if you post them) can find out what that 454 came out of originally . That being said there's a pretty good chance the engine may have been modified from it's stock form.....does it have headers & aftermarket induction like holley , edelbrock , and or weiand ? Who knows what's been done internally . As you can see it's hard to guess the H.P. of this particular engine . Sorry .
