The cars streetability is not a major concern , mpg is not important since I have another car to drive when I dont feel like taking it out. I have heard that streetability on both cams is fine just that they have very lopey idles and have a higher idle speed.
I have friends with eclipses with hks 272s and supras with 272s and have driven them and they do not bother me. Their streetabiliy is fine in terms of drivability they just have the idle characteristics that I mentioned earlier. If anything they seem more driveable due to more power in the low end. I will be running a stand alone with either one of these cam setups. I appeciate all of your guys advice.
