Changed the oil and scoped the cylinders.  They looked really good for an engine that's almost as old as me.  I checked the engine block numbers and verified '68 GTO 400 cid.  The block numbers are 9786133 which corresponds to an engine built in 1967, but more than likely it was put into a car the next year.  1968 was the year of GTO I was told that it came out of.  I removed the hood to make things a little easier.  Replaced the bolt missing from the bell housing.  Here's a picture of the radiator overflow.  Ya, that's a Downy fabric softener bottle.
