I've got a 1978 gmc Jimmy that my buddy parked for the winter without dropping the rad hose... It's got a 305 in it and i'm expecting to have to fix the frost plugs in some manner if it's even salvagable.
I'm wondering if anyone has any tips on what to look for or even a layout of where the plugs are located? I've looked online and couldn't find a good diagram of locations for that motor at all.

My first post, hoping to get some replies! Could sure use the help.

Cheers.

Just fill it with water and see where it runs out. Most of the time it's the ones blocked by the motor mounts that pop out

It's out past cash creek at a cabin. Hopefully it survived. Also hopefully itthe issue isn't behind the motor mounts, not much on that truck that can be 'removed safely' without just coming apart.
