Block heater placement

Where the heck do I put block heater in 1994 454. I can’t find info anywhere. Which frost plug do I remove

Whichever one you can get to.

Is it that simple? Surely you don’t want it on an outside corner

It doesn’t make much difference where in the block you put it. After all, you’re only putting it in one side of a V8 engine, right?

But in reality it may not matter. Mine is just a thought.

That’s my thinking
