70 340 HP handling ability.

Again, I'm not the expert but they say that how you make the power, makes a difference. Supposedly a 700HP NA motor is harder on parts than a 700hp turbo motor. Boost is boost as far as I know so probably a belt driven blower is similar to a turbo in that regard. That 600hp guesstimate is for NA power so 700 boosted may be doable on the stock block. If you can afford a Ritter block, you can probably afford to test that limit on the stocker. Sounds like a science experiment.
