Longblock question

Hey everyone, I own a 1990SC with automatic and my engine has a really loud knock. Since the car/engine has 146,000+miles, i've decided to just change entire engine instead of spending money to fix the problem then have something else break in a few thousand miles.

Now my question is: is there a difference between a 1989-93 longblock and a 1994/95 longblock. Is the 1994/95 longblock a better engine that my original 1990 block? If so, can I just use a 1994/95 longblock.

Thanks,
Brando
