300 HP out of a 318, is it possible with bolt ons?

Obviously compression ratio, stall and gears helps out, of the 3, stall probably gives the most gain, but this idea a reasonable cam can't improve performance on a less than ideal setup is ridiculous. Most dyno'd results I've ever seen on reasonable cam upgrade over stock non performance cam is power practically everywhere. 318willrun's 318 car documented it can be done, it will be interesting to see what converter and gears will add next year.

The goal is more average power to the ground from stall and shifted rpm drops to shift points.
Say 2000-5500 rpm what rpms you gonna spend most average time, even with stock stall and gears ? Probably 3000-4500 rpm followed by 4500-5500 rpm than 2000-3000 rpm, the loss under 3000 rpm would have to be significant to kill the above 3000 gains, plus 2000-3000 rpm hp is 38-57% of torque so you'd need a fairly large torque loss to make a significant hp loss at those rpms.
