Youtube videos dyno 318 magnum stock vs cam upgrade

Here's youtube videos I cam across where guy's do stock ish 318 magnum stock longblock and cam with chinese airgap 650 and headers dyno 233 hp @ 4200 rpm at wheels then swap in something like the cam described below and made 255hp @ 5100 rpm at wheels and made hp at all the powerband rpm over stock cam while adding about 1000 rpm more of usable power. They didn't change the springs which could of gave more revving potential. Not Bad for 318 Magnum with that cam, probably on par with stock 340 performance and still pretty mild. like to see what a more aggressive cam would do like the 380hp create engine cam.
