Just dynoed and looks like 660HP it is. Only problem is this victor intake won't fit under a stock hood. I talked to 440 source and the said rpm performer will work but I will lose 20HP. At this point I don't want to cut my hood on stock 67 coronet. Does anyone have any thoughts on this? Will performer RPM breath well enough for street use?
