Richard Holdener is going to be engine dyno testing the 4200 next week, in stock and then boosted (turbo) on a stock motor. He posts on youtube nightly when testing.. Should be good to watch

51 GMC 4.2 turbo

For enquiring minds, right now the best run is 555hp and 578ft.lbs. That was with a junkyard 4200.
