Correction thats 11.0's in a "street car" full interior,full exhaust...i'm willing to bet the cars you speak of are all striped down race only ...thats like comparing apples to oranges..you can't,and trust me i DON'T know it all but, have run nothing but 340s and 360 to know what they can do...And i'm willing to bet theres a LOT more cars running 10's now then there were back then..
