With much help from this forum, I just did an engine swap on my daughter's 98 Grand Prix GT (normally aspirated).
When I purchased the car, it came with an extra L36 with ~80k miles.
However, the reason why I didn't swap that engine in at the time was because someone removed a main bearing cap and bearing, but didn't mark it. (not me - honest!)
So now it is an extra engine that I don't know what to do with.
Is there a way to tell how the cap was originally oriented?
Any suggestions on what to do with it? I'd hate to scrap it if it is a good engine.
