Answer
Rodrigo-

  It depends which model it came out of.  On average I'd say around 200hp or so with a compression ratio of about 9.0:1.  With a carb'ed motor you might make a few more horsepower, but your fuel economy will tank and carbs are a pain to swap onto an EFI or TBI motor since you have to do a good amount of tuning just to get them running right.  You won't change the compression ratio, though.  Hope this helps.
