Without this descending into a flamewar, I beleive that you read that wrong. The cam was not a 130hp gain, but a gain TO 130hp. If it were so easy to get over 250 hp from a 2.3L, why would anyone do a 5.0 swap? Assuming 10% drivetrain loss, you're still talking about putting 225hp to the wheels, the same number that a stock 5.0 puts to the crank. Assuming this is true, your bored/stroked 2.3L (which I'm assuming now is a 2.9L) is now making 283hp to the ground, assuming that the motor is still operating at the same efficiency as it was before. Now, as we all know boost acts as a multiplier, every bar (~14.7 lbs) of boost basically adds another 100% of the NA power, so a 12-14 psi turbo is now taking this motor to 566 hp AT THE WHEELS. And that's not a lot of boost. if we run 18-21 lbs, that's 707.5 hp, again at the wheels.
Basically, you show me dyno numbers of this 269hp NA 2.3L, and I'll believe it. Until then, I call bullshit.
