Quote: I have an srt8 challenger and my mom has a hemi 300 and i am just amazed how fast they are for a stock vehicle. I remember back when my 68 383 roadrunner was basically stock and this heavier car with smaller engine would eat it alive. every time i drive it i keep saying this thing cant be stock and i was curious is it the head flow they have now or is it the efficiency of new engines] now or is it just a comination of many things
This pretty much sums it up. An engine is only an air pump. Pump MORE air, do it MORE efficiently, you make MORE power. Pretty basic.
