ZC swap into 97 civic EX

i have a 97 EX with a blown motor... a friend of mine has a d16zc and he's sellin it to me for $100... but my question is, wut trouble will i run into when doin this swap? he said it will bolt right up to the tranny in there... also the ZC is non vtec, will it use the same harness? has anyone performed or seen this swap before?
thanks for the help guys

ZC's are out of cars that are older than 97 (as far as i know) and in most, if not all states, i don't think they'll let you do that......might want to check on that.

well in FL they don't do smog an all that stuff so it don't really matter wut engine u got in your car down here
