Difference between motors

I have a 90 that i threw a rod in last weekend i have a 92 motor my friend gave me my block is still good but my crank is jacked. the head and crank are still good in the 92 motor if i put these on my block will i make up the extra 10 horses the 92-93 motors had over 90-91 motors. if thats not it what would make up that power.
