*2 on that one.
They have a reputation for their SC's blowing alot of Hemis. If I remember correctly it happens because of not getting a proper fuel-air mixture through the intake manifold to two of the cylinders.
Basically six of the cylinders would run slightly rich, and two would run very lean... The lean cylinders would then eventually wear and blow the engine.
In other words, too much boost through the current intake manifold = blown engine. Most Hemis haven't had much luck getting beyond 6-8 pounds of boost so far.
You can find alot of this info on the chargerforums and lxforums.
Edit: That 300C looks to have a different intake manifold now that I look at it more closely... That could fix the problem.
