At what fuel pressure? With stock fuel pressure, you're super safe up to 285 rwhp, and can stretch it all the way to 310ish rwhp.

With a better pump, you could push well over 400rwhp.

I hope the inspiration for this thread was not to see the max horsepower gain of 24# injectors and a 190lph fuelpump on a bone stock 5.0

24 lbs injectors at 100% dutcy cycle (open all the time) will flow 120 lph. You still need about 20-25% coming back through the return line, so for a NA car at factory fuel pressure levels, all you really need is a 155 lph pump.
