Engine

i had a used engine put in my 99 park ave ultra, what type of questions should i have are there certain things a good mechanic will automatically do they told me they will put on the best parts of the 2 engines, besides oil what are some other things that should be done, just looking for all the responders i can get for much info… much appreciative for any info

i think its too late to ask what should be done, since you already had it installed. hopefully you use a good reputable mechanic. go talk to him and ask him what he has done, and what you both expect.
