Nitrous!...on a cast piston 360
I remember mopar lover, and nitrous guru Monte Smith's critique of that EM episode. He basically said that they screwed up, that that engine shouldnt have grenaded with that amount of nitrous. He said that they didnt pull nearly enough timing out of it, it didnt matter how slow you ramped in the hit.
Even though i have zero experience with nitrous (yet, ive got a 250hp edelbrock system) ill bet Monte was right. Tune, as always, is EVERYTHING!
