Can I swap a 4.3 engine for a 2.8 in my Chev S-10 Blazer?

I have a 1986 Chevy S-10 Blazer that is in very good condition. The only objection I have is the 2.8 V-6 engine does not have enough power. The later models went to a 4.3 V-6. How much trouble is it to swap the engine for the 4.3?

Update:

The 86 has a lot of sentimental value.

    GM offers a 3.4 replacement motor for the 2.8. Its a direct bolt in. Have installed several in the past and had good luck with them. Call your local dealer and check them out..............md
