Just got a 85 K10. It had a 305 originally that was swapped for a 350. I tried to replace the oil pan today but the holes didnt line up! Also I ended up buying 2 different gasket sets and neither fit on the bottom of the motor... I am trying to figure out if maybe I have a pre-80s chevy 350??? Trying to get this oil pan replaced because it was leaking horribly and the plug was stripped really bad. Any knowledge would be really helpful!

You will need to look on the block behind the drivers side head at the back of the engine and find the block Id #, then you can find out if it is really a 350 first, and what year range it is.
