Auto Parts: motor compatibility, different computer, 8l

Question
will an 85 Chevy S-10 motor I think it's a 2.8L fit into a 94 chevy S-10?

Answer
    They stopped using the 2.8 in '93, so it would be a world of difficulty to get it to work in a '94.  The '94 and later trucks use a completely different computer system, and the 2.8 is not made to accommodate it.  Try and find the right motor, or convert to a V8 if your local emissions laws allow it.
