Wow, that's an old post.

Brings back memories.
The only reason I recommended hand cranking was the first time I ever did this, I must have poured like 6 ounces into each cylinder, let it sit for 15 minutes, and then cranked it with the starter.
The LC pumped all over my fenders and the hood.

What a mess.

This was with an '87 355 V8 in a Suburban.
The two important items are to let it soak at least an hour (preferably overnight) before cranking, and then make sure the LC has soaked past the rings before replugging.
And oh yes, I recommend you change the oil after you do this.
