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

Rick Ehrenberg at Mopar Action has been saying for years, a factory small block is only good to 550 hp before they split apart. He's probably the single biggest source for spreading this misconception.

That would only serve to make more sales on 'R' blocks and such. I wonder who he's in bed with, and what he stands to gain by spreading that rumor.
