89 camaro diagnostic

Ill be doing some homework but in the mean time I would like some input on what needs special attention on an 89 iroc z28. Im not too savvy on the Camaro so Im taking it into a mechanic and have him look it over. What I know is its a 1989 IROC z28 with a '97 camaro engine (LT1 I think?) I will ask to have a basic diagnostic of the engine and tranny but I was looking for any other helpful hints on where to check for major problems.

Thanks for any help!

not really diagnosis but if it sounds too good to be true it might( dont know if u own it or not)if not check kbb for price for your area

If you can get a pic of the engine bay, we can tell you for sure what it has.
