I have the Indmar small block (looks just like the pic above). I do remove the knock sensor carefully. Without removing the electrical connection. That allows that side of the block to drain. The electric connection will spin freely if you hold it in one hand, while turning the brass fitting with a wrench. Then I replace it.

Small block uses the drain hole for the knock sensor.

Would only be on fuel injected engines, and maybe not even the TBI engines since the fuel pressure is so much lower and they are not as prone to vapor lock.

It's a TBI

When I helped with my friend's big block Echelon, I wasn't totally confident, so I just opened every hose and drain plug I could find. Found a lot of water. It worked, though!

That's what I'm thinking too!  And then fill it with RV antifreeze.

Do you have the block drain below it as well, or just the one drain?

Just the one drain hole (that holds the knock sensor). As I recall, there is no other places on the block to empty. Just the single hole on each side. (various hoses, etc. though that need emptied)
