engine swap

I have a 1995 grand prix that has a 3.8 in it and i had a 3.1 from a 1990 berreta given to me. Can anybody tell me if this will be a clean swap?

wait a sec are you trying to tell us that you want to swap 3.8 with 3.1 ?

yea when the engine is free and the 3.8 has a cracked head.

Hmmmm.... well if my Beretta can accept a 3.8L from a GP, your GP had better accept that 3.1L, or else there must be something wrong with the world....lol
