I saw that one while I was at the ice drags.
If memory serves, that was a 350 crate motor from a - um - well know aftermarket performance company (to remain nameless). I think something happened to the motor after it was initially fired and it got sent to Norm Brandes in Wisconsin. He tore it down and was disgusted - it wasn't even clean inside, never mind machined and built properly. So he went completely thru the motor, remachined everything, and put it together with an eye toward lower emissions. The rest are History.
