What am I supposed to have? Paxton lists a stocker @ 300HP, that's crank HP right? That makes 470HP @ the crank?! If I figure 80% of that for power train losses, I end up at 376HP, if my math is off, let me know.BTW, something that troubles me, I've heard the rods don't like much more than about 450HP, true?

Brenspeed installed my Paxton 2200 h.o. last March,and did the custom dyno tune, I'm at 455 rwhp. Brent said there was more rwhp to be had but I didn't want to chance blowing the motor so I had him leave it at 455 rwhp at 6200 rpm.

p.r gt

dyno last night 435 rwhp and 410lb of torq, all the run were close , i mean hp and torq

It all depends on your tuning along with many other things. The magic number on hear seems to be around 450-500whp max on stock internals,I wouldnt wanna go over that if it was a daily driver.

Its torque that snaps your rods because your engine doesn't make "horsepower", as thats only a calculation of RPM x Torque output / 5252. Horsepower is the "rate" of torque output.
Centri's will produces 480 rwhp at 6500 RPM, but peak torque is only 410ft-lbs. A twin screw will produce higher torque numbers, slightly lower HP numbers, but produce that torque lower down in the rev range.
