80/20 Rule

without a doubt...a high horsepower number usually comes at the cost of lo rpm performance.
Many well built engines are good performers on the strip but poor on the street unless you use
3.9's or 4.10's and a high stall converter and then not pleasant to drive on the street.

True but it's that middle ground how much cam, how high gear, how low stall, displacement size for hp etc.. before your car isn't streetable and what does person X consider streetable in the 1st place that cause these 10 page discussion :)

My 380 hp crate engine with a 2800 stall and 2.96 gears is somewhat unstreetable, It's how the car came when I bought it, definitely deeper gears and or a smaller cam would help with the under 2000 rpm or even a dual plane. But for the most part I find it pretty acceptable, Have to drive in 2nd in town or it lugs. And only get a true sense of it's power when I do 40 mph in 1st then drop the hammer, But it still can smoke the tires and pulls pretty good from a stop light. To some it's not a streetable package and some it would be acceptable.
