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

Can you go into more detail on what you are using for Boost? Is it Supercharged, Turbo's or Blower? Plate mounted so your on the Juice too?

What head gaskets were you using when they lifted?

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 ;)
