Really? I've never seen a single one. By having at least one rubber mount on the passenger side, all the vibrations have a place to go. The solid on the driver's side doesn't move at all, and it can't break.

I've never seen a block break because of this. With all solid mounts, I've seen the stock block bosses break in extreme applications, but not with a mix.

Interesting...

We mount most of ours solid.......Motor and trans!

Mount it with good poly or rubber mounts, then chain the drivers side. Driving around all is smooth and it won't vibrate you to death.

When you decide to get down on it, the chain will do it's job and you won't have to worry about breaking a mount.

I ran a BBC with 650 hp. It worked like a champ and it is an easy AND inexpensive way to solve your problem.

Chaining is a horrible idea, that would snap a block instantly off the trans brake for sure! If it ever gets a hard shock it could break the block, for sure if it is an aluminum block.
