Engine codes
 

Ok, so I am a real noob about this. Started trying to figure out exactly what the motor was in my new truck. What I found was the back casting 14010207= '80-'85 350 4 bolt truck. But when I get to the front numbers V0608SUN=Flint/June/08 day, and then there's SUN. Cant find this ANYWHERE. I checked this 4 times and it IS stamped SUN. I found SUH but no SUN. Can anyone please help me with this as I am just trying to know as much about this truck as I can because it's just my anal-retentive way. :)
