I think that is going to be hard to come up with. The largest engine offered in any Blazer in 1972 was the 350 cubic inch engine. This website says they were good for up to 200 HP: https://www.classicmuscle.com/resour...trucks-history

Now, if they will allow you to go with the vehicle class, the largest engine in the 1972 C/K class was the 402 cubic inch big block which was rated at 300 HP.
