I guess it would depend on your definition of "street use"!! If it means a 4500 stall or a G-Force 5 speed, Lenco, or the like and you have an engine and drivetrain capable of doing 8,000 RPM shifts you have way too much head!!!! A set of out-of-the-box Performer RPM or equivalent are more then adequate for street use!!!

You could sell them to one of the guys who run the big, lopey cams on the street and they could really wow the troops at Sonic!!!!!
