8 3/4 gears

I will add there is no true definition of "streetable" just ask the real street outlaw guys. It really boils down to what a person feels comfortable with on the street. If you are going to build an engine a certain way then the drivetrain needs to follow it regardless or it will drive like crap. As far as tuning that is something very few are really good at and it makes all the difference but even the best tuners can't make up for a poor combination to start with.
