I am going to check out a New Northstar engine for sale this Saturday. It has been in this guys (our Director of HR 60+ years old) garage for a year covered up and on a engine display stand. He says it has everything but a starter and valve covers. He says it is a late 90's engine that his son brought home from a dealership that closed down. He wants it outof his garage. What should I look for and what is it worth. I own 2 Chev. HD pickups and a few motorcycles. My Mom owns a 2003 Cadillac.Thanks for a response.
