Street car. I am going to run a 4 speed overdrive. With the .73 overdrive gear, my final drive with the 4.30 will be 3.139 so it will be very streetable.
If I were you though, I would concentrate on getting the engine running in peak form first. It can easily become overwhelming if you try to look at it all at the same time. Work on one section at the time and take your time and you'll get it done.
