I agree. I don't see many 11 second cars driven in. I see even less on the street driving around. At least where I lived and now live.
I had a customer who loved to tell everyone he had a crate engine mustang street car that went 9's.
I did go 9's. It wasn't a crate engine. It came out of the shop I worked at, and had my porting and intake mods. It never saw the street, unless you can't backing it out of the shop and driving around the building.
