There are too many things that this engine excels at like no other 400 I've seen! The fact that it runs fine on 91 octane @10.1:1 CR with iron heads is an outstanding accomplishment! The second amazing thing to me is the power and low end torque! Seeing is believing! I think this engine will destroy a lot of egos very soon!
