One of IQ52's competitor's used a 361 in the fall of 2011's Mopar Muscle's engine build competition. If i remember right though, a valve hit the piston on that build.
In the competition they ran Jim's motor on the dyno without any coolant flow...
Those builds all were capable of sick power. Even after castrophe Jim's big block squeezed out over 700hp with a few repairs. His valve guides got too hot among other things..
