I have an old 350 in an old school 6" lifted Nissan body that's been sitting for at least 5 years. Any advice on what to replace and where to start on getting her going?

 

Going to need a lot more info on this diagnosis. Year of the engine. Why it's in a Nissan. What codes do you have?

 

Not sure the exact year of the motor but long before computers lol it's on an old school lifted Nissan pick up body, my guess is mid 80s. I'm just wondering what to look for other than flushing old gas and oil, and giving the carb a good clean.
