**600hp sbm block limit? Or is it bs!!**

Well i got no pics, but if your looking for more than 600hp i know that using mounts on the block will show the walls are effected by using a mount...same holds true for the bb's
So you want to use ears when you get beyond 450hp...
Are you using a la or mag.... i wouldn't trust a mag block

I am using a 1973 LA Block on mine.
