yeah i agree....lots of the muscleheads with their 5.7liter+ sized v8's run into steetablility issues when building a 450 whp all motor engine. and u claim uve seen it out of 3 liters? the pistons and cams would have to run ludicrous compression and duration along with revving the bitch out to 10 grand before ud see that kind of power. proof is definetly in order here.
