So from what I have read, for the most part, big or small block, to get this mid 9 second street car (N/A), you have to be very light at around 2900 lbs, lots of converter, lots of gear, lots of compression, big cam (which means stiff springs). All of that hardly equates to a "street car" that can be driven anywhere at speeds faster than 50 mph, no mileage limit, little maintenance, IMO

If it is so easy to run mid 9's N/A how come you don't see it that much, much less in a very streetable street car?
