There won't be any HP difference in the block.
It will bolt in with no problem. The only thing that might be good is it could be a 4 bolt main depending on what it is. Do you know the engine code on the 1970?

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
