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

You have a misread on his post. He meant he lifted foot off pedal at 6200rpm while on Dyno. The head gaskets were good. And by plate mounted he means how engine is attached to frame, no stock motor mounts. Just an FYI for ya ;)

Yeah I do that sometimes. He was talking about his head gaskets not giving out so I assumed........ My bad on that one!
