I will be running this on the street as well, cruising speed at 65(to and from the strip) about 20 min one way so I do need that O/drive gear.
Right I don't want tons of power, my87Z had it right; 430-470hp and 440-480tq range and I very much want a roller cam.
I talked to a friend and he immediately recommended gears in the 5+:1 range with a 5 speed.
As for weight I'll be gutting the car, engine bay and interior trying to drop as much weight as possible; thinking about getting rid of the power steering (racing seats if budget allows.) I'm not too sure about what weighs the most that you can get rid of really, so suggestions are welcome. Power to weight is something very important for sure.
Suspension is a whole other ball field, I'm not really to that yet but I'll be looking into it.
As for tires I'm gona go with a pair of slicks at the track(not sure on the overall size yet) and then just some cheap street tires.
